Ibutamoren: Oral Growth Hormone Release

Looking for a potent GH release that doesn’t involve needles and frustrating timing schedules? Ibutamoren (mk-677) may just fit the bill…

I have always been a huge fan of Ipamorelin and CJC1295 (modified GRF 1-29) when it comes to increasing Growth Hormone levels. But those two peptides require injections, and to really see benefits, you have to inject it multiple times a day, and plan your meals out accordingly (you want to be fairly fasted before using these, and then wait for at least 30 minutes before eating afterwards). So for those of you who don’t want to jack with all that, and want a continuous, 24 hour increase in GH, IGF-1 and IGF-BP3, then Ibutamoren, an orally active GH secretagogue may be just the ticket.

The benefits of Growth Hormone on metabolism and lean body mass are undeniable. I also go to great lengths pointing out that I don’t think GH is much of a muscle builder per se, and that its ultimate benefit comes down to controlling, or rather off-setting, the detrimental effects of insulin on body composition, when it comes to excessive fat gain. Insulin and IGF-1 are amazing at increasing protein synthesis, no doubt, but the real benefits after extended trials of anything that increases GH levels seem to come more in the way of increased leanness, and decreased fat storage.

For many, the use of HGH is not only too costly, but is not a good route to go if overall health and longevity is of utmost importance. HGH, injected exogenously, can create a really awesome environment for body transformation, but with that comes the price of shutting down the HPA production of natural pulses, which interferes with an overall healthier body, for lack of a more scientific term. HGH is great at doing what it does, but leaving it “on” for 8 hours post injection, can lead to insulin resistance and water retention imbalances that ultimately take their toll on the body, especially if someone is using large doses. GH is not supposed to be a 24 hour ON button. It is supposed to peak and drop, along with other hormones, to create the perfect environment for long-term health and anti-aging benefits.

Enter the injectable GH releasers such as Ipamorelin and GRF. These are very, very good at getting the job done when it comes to increasing the body’s own production of Growth Hormone. The biggest problem, though, is that to really take advantage of the benefits, and to fully utilize the peaks, a person would have to inject multiple times a day, and plan out their diet accordingly (too much food in the gut will dampen the release and peak of the GH).

But with an orally active version like Ibutamoren, a single dose can increase benefits throughout the entire day, without the need for carrying around needles, watching your diet before and after injections, and all that crap that goes with playing with GH releasers.

And the results from the studies I’ve seen, show promising results.

Here is a graph showing the benefits continued to come over a year using Ibutamoren. In many instances, these GH releasers would fizzle out after a month, so seeing a consitent benefit over such a long period is a huge thing!

Effects of a 7-day treatment with a novel, orally active, growth hormone (GH) secretagogue, MK-677, on 24-hour GH profiles, insulin-like growth factor I, and adrenocortical function in normal young men.

To assess the effects of prolonged administration of a novel analog of GH-releasing peptide (MK-677), nine healthy young men participated in a randomized, double blind, three-period cross-over comparison of orally administered placebo and 5- and 25-mg doses of MK-677. Each period involved bedtime administration of the drug for 7 consecutive days. At the end of each period, plasma levels of insulin-like growth factor I (IGF-I) and IGF-binding protein-3 (IGFBP-3) were measured at 0745 h, and 24-h profiles of plasma GH and cortisol were obtained at 15-min intervals together with the 24-h urinary excretion of free cortisol. Profiles of plasma free cortisol were calculated at hourly intervals. The amounts of GH secreted were similar in all three conditions, but GH pulse frequency was increased with both dosages of the drug, primarily because of an increase in the number of low amplitude pulses. Plasma IGF-I levels were increased in a dose-dependent manner, whereas IGFBP-3 levels were increased only with the highest dosage. There was a positive relationship between GH pulse frequency and IGF-I increase. Except for an advance in the nocturnal nadir and in the morning elevation, MK-677 had no effect on cortisol profiles. In particular, 24-h mean levels of plasma total and free cortisol and urinary excretion of free cortisol were similar under all conditions. The present data suggest that the use of MK-677 for the treatment of relative somatotropic deficiency, particularly in older adults compromised by such deficiency, deserves further investigation.


And a quick note about the cortisol effects… A lot of these peptides increase Cortisol, which is definitely not wanted during the peak of GH release, if physical transformation is a goal. Many of these also increase Prolactin, which can cause a lot of other side-effects.  So an orally active GH releaser that doesn’t increase Cortisol is definitely going to be a game changer.

Two-Month Treatment of Obese Subjects with the Oral Growth Hormone (GH) Secretagogue MK-677 Increases GH Secretion, Fat-Free Mass, and Energy Expenditure

We conclude that 2-month treatment with MK-677 in healthy obese males caused a sustained increase in serum levels of GH, IGF-I, and IGF-binding protein-3. The effects on cortisol secretion were transient. Changes in body composition and energy expenditure were of an anabolic nature, with a sustained increase in fat-free mass and a transient increase in basal metabolic rate. Further studies are needed to evaluate whether a higher dose of MK-677 or a more prolonged treatment period can promote a reduction in body fat.


Another quick point. IGF-BP3 increases are a good thing. In some instances, we see a binding protein and think of SHBG, Sex Hormone Binding Globulin, which arguably makes Testosterone less effective. In this instance, however, the binding protien IGF-BP3 is needed to carry the IGF-1 into the cell and activate the receptor. So anything that increases IGF-1 AND also increases BP3 is a definite benefit.

  1. Good product.

    Posted by Unknown on 30th Aug 2019

    Seems to be very effective at low dose per day (10 mg) : more hunger and better recovery.

  2. Turn your supplement stack up to 11.

    Posted by Leo on 5th Aug 2019

    My supplement regimen is quite extensive. Over the years, I've experimented with a plethora of substances, from herbal extracts to highly engineered compounds, all in the pursuit of enhancing my physical and cognitive performance, with minimal side effects.

    MK-677 became part of my stack several years ago. 20mg per day dramatically improves the quality of my sleep and speeds recovery from workouts and injuries. It also helps to protect my joints and keep my skin clear, while elevated IGF-1 levels mean I stay relatively lean even when bulking, with higher potential for muscle hyperplasia.

    After doing my research, I switched to DNA Anabolics from another brand and have been consistently pleased with their products. So much that I've introduced several friends and family members to their SARMs and other products.

    As for side effects, water retention and vivid dreams ought to subside after 2-3 weeks, depending on diet. Then, we merely have to contend with mild hunger and occasional numbness in the extremeties. Of course, increasing the dosage will exacerbate these effects. However, I typically eat one meal per day (mid-afternoon) and rarely find myself ravenous or uncomfortable.

    Overall, an excellent product from a noteworthy brand.

  3. MK677

    Posted by John Holt on 11th May 2019

    I Have revIewed your MK677 on my you tube channel (^^^^) it is excellent and have been using now for 14 months, and have 12 videos explaining how I have altered dose etc over the 14 months. excellent product !

  4. Works great

    Posted by Ned on 8th May 2019

    I'm using it at 10 mg dose a day. Sleep improved on the first dose. Hunger is substantial. I've noticed I recover faster. Been only 2 weeks since taking it. I would have problems building muscle as I naturally have low hunger so this helps me with caloric intake. Definitely works.
    Never taken anything else so can't compare. Also starting with lower dose is better I might increase it if I see a plateau. At the moment 10mg a day is doing great things for me.

  5. Works brilliantly!

    Posted by Dominic Butler on 12th Apr 2019

    I have been researching Sarms and other similar products for some time now. I finally made the decision to jump on the wagon, and I am glad i did. I have been taking mk677 for two weeks now, the first week I was dosing at 10mg and thats what got me hooked. At the second week I jumped up to 20mg a day and the benefits are real. Strength has gone up in bench by 7.5kg. Yes it has made me bloated, however I never had the side effect of feeling hungry, but instead I can eat way more than I used to without getting full. The pump in the gym is awesome, way better than any 'pre workout' sup ive used. The muscles feel hard and pumped, and have seemed to develop a better mind muscle connection. In a day to day routine it has made me feel more confident and definitely helped with my mental health and wellbeing (borderline personality disorder). Looking forward to trying out other supps and am going to make the big jump and stack it with LGD 4033 next.

  6. very good product

    Posted by Unknown on 4th Feb 2019

    I’m using it more then few months. Keeps me hungry so
    I can eat a lot! Giving me good rest! who ever thinks to have it worth to try!!

  7. no change yet

    Posted by Unknown on 4th Feb 2019

    Been taking for a week now, maybe that isn’t long enough. But I don’t feel anything. No hunger, no change of sleep, haven’t gained any yet, in fact I’ve lost weight.
    Maybe it takes longer than a week before it works?

    JW Replies:
    It usually takes two weeks before seeing any results however this always deoends on the individual as well as diet, exercice and lifestyle. The weight loss is already hapening which is a good thing as MK-677 is supposed to increase your hunger so your protein intakes helps with muscle growth whilst still leaning.

  8. Best standalone supplement Ive ever used

    Posted by winchesterx1000@gmail.com on 20th Dec 2018

    This mk677 is by far the best supplement you can buy that actually has a ‘tangible’ effect. I’m a big proponent of real food only and don’t use anything else; creatine, whey, bcaas, even preworkout, I strive to get all of my nutritional requirements from my proper diet. Mk677 however is proven to increase HGH levels in people, and igf-1 levels at mid to high doses, something I cannot otherwise get as an effect from consuming something. I use this at 30mg a day and each time I cycle I experience all the positive effects, I lose a little body fat, mass and strength goes up, nothing outrageous but very noticeable for a product with basically no unreasonable side effects, and as I previously said it’s a standalone thing, no need for a Pct or any other supporting product, just take them and that’s all there is to it. The longer you use it the better, since the effects are cumulative, seem to be linear in that they don’t taper off and the rate of gains stays the same for the entire use period. My current plan is to use it at 30mg a month for another 10 months straight and see where that gets me. Fully recommend this product, thanks JW!

  9. good product and very good service.

    Posted by YM on 14th Dec 2018

    I was very impressed with service.
    Good product, caring staff

  10. Perfect!

    Posted by Sam on 30th Nov 2018

    The product is good. Noticed changes straight away. I've only been on it for 2 weeks and I'm literally growing after every training session. I'm doing only 10mg before bed. The pumps on this are awesome. It is good to have some inositol and choline supplement, just to keep the liver healthy. I haven't seen noticeable increase in strength for now, but we'll see how it goes. Had a little problem with cramps the first couple of days, but I have adjusted my potassium and magnesium intake and everything is back to normal now. Also it's good to monitor your sodium intake while cycling this, because of the water retention, but depending on your body fat % it can actually be a benefit, because the muscles look fuller. Overall very good product.

  11. the best MK 667 in capsules on the market

    Posted by Marcin on 20th Oct 2018

    I've tried many different brand of MK 677 (caps/tabs) and without a doubt the DNA Anabolics MK 677 is second to none on the market! On only 20mg e/d you can fell the benefits after a couple of days. improved the sleep pattern, lean body mass and increased appetite(for someone this can be side effect). It goes better when the dose is increased to 30-40mg, side effect are mild and not harmful (for me) and these are such as lethargy and numb limbs sometimes. The best thing is that even when I was off from gym for 6 weeks and still used 10-20mg e/d, my muscles/strength were not dropped significantly and was much easier to back on track when I've started training again.
    Thanks JW SUPPLEMENTS to have this product for sale!!

  12. Great Sarm

    Posted by Andreas Alm on 19th Jun 2018

    Great product so far! Before I start my review, let me tell you something. I were a skinny guy who spent alot of time at the gym and tried to eat as much as possible (high calorie diet). But I struggled with "hunger feeling". No matter how much I pushed myself to eat every third hour, I still didn't get the feeling of being hungry. So I heard about this product. What you should know is that this product rapidly increases your hunger. That's why I mainly started to try these. Let's get back to the review shall we?

    Started my bulk cycle off with only using MK677 for 2 weeks. Taking 20MG/day (2 capsules before bedtime).
    During the first week I didn't see any physical results in lean body mass (didn't expect to do so either this early). However my hunger had increased alot and I ate about 5-7 meals per day with a hight protein and calorie intake. On the second week I started to notice the difference. My body shape had started to change and my muscle growth had increased and also my endurance.
    Third week, I stacked these with Tr3st from OL and here is where the magic happend.

    Did a 4 week cycle with Tr3st toghether with MK677 (had MK677 for 6 weeks).
    Gained a total of 15KG. Have been on my PCT (You don't need a pct if you're running mk677 only, why im on pct is due to the Tr3st) for two weeks now, using "Perfect PCT" and haven't felt anything negative. My endurance is great, stamina is great and my libido is great. The best part, haven't lost a single "KG" during my PCT.

    To this I also have to add that I hard a strict food schedule of a high protien and calorie intake. Went to the gym 6 times a week with a professional workout schedule.

    All this being said, I strongly recommend this product and as mentioned above, if u looking for serious mass gain these are perfect to stack with.

  13. Great stuff.

    Posted by Del Bains on 28th Mar 2018

    Great stuff, I'm sure it is working. I feel the difference. I'm sure it's not a placebo effect. Will buy another.

  14. Slow and steady

    Posted by Nox on 13th Mar 2018

    This is the second bottle I have run, so have been using mk-677 at a low dose for a month and a half.
    Despite my diet not being the best it could and my training being a little off the boil I've kept some decent muscle and strength. I'd definitely recommend mk677, but I wouldn't expect big results like a course of test. After a month I haven't noticed any adverse side affects, a little bloating from water retention early on, but that soon passed.

  15. mk667 update

    Posted by Fabz on 10th Mar 2018

    good product would highly rate it a good source to buy from.good pumps in the gym great restful sleep woke feeling full of energy for the day.I also had really weird dreams while taking mk667 an strange tingle sensations in fingers an hands.I would say this product is good as a great well being supplement so far as only been consuming for 4weeks so far so good!!

  16. Sarm MK-677

    Posted by Unknown on 5th Mar 2018

    Been on mk-677 for 2 weeks. 20mg a day. 10mg in the morning and 10mg before bed. No result yet only been 2 weeks. No change in the gym no added strength.
    Going to give it 2 months. Hope these mk-677 are legit.

    JW response:
    MK-677 is best taken if both capsules are taken at night.

  17. Used several bottles

    Posted by Allan VanHofwegen on 31st Jan 2018

    My wife and I both take one capsule each evening. Good pumps in the gym and vivid dreams during sleep. Slight increased water retention. I like this product. We are both in our late forties. Good alternative to growth hormone. My wife did not like the water retention she experienced from growth hormone.

  18. 100% real

    Posted by Unknown on 11th Jan 2018

    Legit mk677. Good pumps, sleep and recovery. Super powerfull. Took it before bed. I think 20mg is sweet spot for me . Felt lethargic and sleepy all day first which subsided after couple weeks.

  19. very goodstuff

    Posted by andy on 5th Dec 2017

    Been on mk-677 for a few months now using different brands, this brand is good and I can tell it's working as my wrists are slightly larger and the sleeps I have now are much deeper. I get the occasional wave of intense hunger but this can be countered with drinking lots of cold water, bf seems to be steadily going down but most likely 95% due to diet. All in a good product l use it mostly for the feel good factor and better sleeps

  20. Not so sure

    Posted by madsie on 4th Dec 2017

    Taking 30mg morning empty stomach, I am having deeper sleep and wild dreams, but strength still the same, I've read that mk677 is extremely bitter to taste..this however is not! Crack the cap open tastes more like flour to me ........??

    JW Supplements replies:
    If we could take the opportunity to explain that it’s inevitable that you would be aware of a flour taste because all capsules manufactured have to hold all the metric that it can hold therefore if the capsules contains 10mg of mk-677 its natural to add the filling agents such as maltodextrin or rice flour and it would be almost impossible to taste the mk-677.


  21. Average

    Posted by Jo A. on 4th Dec 2017

    I have to rate it average, because after a week I really can't say if it works or not. I really don't feel a thing, one way or the other... No hunger yet, no extra strength in the gym etc.. Actually down feel a thing. Hope it will kick in though..

  22. Super strength And the best

    Posted by Simon on 9th Oct 2017

    Ive purchased this 3 times now and i can honestly say its the best mk677 ever. Ive used many different brands with ok results, but this is the ultimate, i take 20mg a day, i feel everything you must feel when taking mk677 and ive researched this chemical throughly, my strength, size has all gone up, i suffer from bad psoriasis (eczema) its basically almost cleared my whole body, not that i brought it for that purpose but it is an effort of mk677 anyway so a bonus for me. once you buy once that's it you wont buy any other brand. Thanks JW

  23. 4 SARM STACK in France :)

    Posted by Anonymous on 7th Oct 2017

    I am French sorry bad English ... I stacked 4 SARM MK2866, GW, LGD MK677. I started one after the other. today I am 12 weeks MK2866 / 10 weeks LGD / 8 weeks GW and 4 weeks MK677. I stop GW and keep MK2866 MK677 and LGD up to 20 total weeks. The Mk277 and the one that gave me the most results was 20mg / day empty belly in the morning. I will raise it to 30 mg.
    The rest of my stack will be 30mg MK2866 / 30mg mk677 / 9mg LGD per day in the morning in an empty belly grip.
    No side effects other than it gives hungry. I feel really good

  24. Mk 677

    Posted by Lee on 5th Sep 2017

    Tablet size large and doesn't seem as strong as competitors

  25. good stuff

    Posted by Unknown on 31st Aug 2017

    Been taking it now for about a month at 20mg a day. Can’t fault it. Takes a while to kick in but I’m feeling stronger at the gym now, don’t seem to ache as much as I used to, also muscles are starting to feel a lot fuller. I am going to try run these for at least 6 months. No side effects yet apart from numb fingers first thing in the morning but this soon passes

  26. good so far

    Posted by danny on 18th May 2017

    ive been taking 20mg/2 caps for a week now so its still early days to make a big comment . One thing i have noticed already is the extra energy levels and drive its given me. still lifting the same weight and reps but like i said i do feel alot more energtic and better about myself. ive been lifting for over 6yrs now and tried alot of supps and now ive come across sarms so im given them a go. would like to write anothet comment once i finish my cycle. but so far so good

  27. Three months in

    Posted by Unknown on 25th Apr 2017

    After three months it is save for me to say that this is working for me. The extreme hunger which I've experienced in the first month is gone. Fat is going down and muscle is steadying going up. I will be continuing this product for at least 6 months. I'll keep you posted!

  28. Dose before bed or you'll be hungry!

    Posted by Simon M on 21st Apr 2017

    3 weeks in and it's helping repair a tendon flairup. My skin tone has also improved and if I take in the morning, I'm starving, so everything you would expect. Recommend.

  29. it works

    Posted by bmarkulis@gmail.com on 7th Apr 2017

    I've tried 3 or 4 brands already and this one seems to actually be working. I was usually taking it in the morning so wasn't really seeing full effects after some time (once hunger and lethargy side effects were no longer persistent) but after having 2 weeks I started taking it before sleep. I slept deeper, was better rested in the morning and straight away had some vivid dreams about climbing, falling and stuff... definitely works

  30. Nice product

    Posted by Unknown on 23rd Mar 2017

    I've been using this for over a month now. Really noticing an increase in appetite and deep sleep. Haven't experienced a lot of fat loss yet (have been eating quite a lot due to the appetite increase). I'm starting a deep cut in a couple of weeks and am planning to run the mk-677 for about 5 to 6 months.

  31. super

    Posted by Sen on 10th Dec 2016

    Firstly im scared from this product . i thought its bunk with no effect but its awasome. Ive run and of pct and i feel far far better. Its a very good product for accaptable price. I highly recommend for everybody

  32. Great Product, Trustworthy Company

    Posted by HP on 8th Dec 2016

    Great product, attempting to repair RSI wrist damage, some improvement, great deep sleep, didnt notice the hunger increase.
    Due to increased HGHproduction , your body goes into repair mode and craves sleep, May leave you feeling tired/hazy.
    I swork a 9-5 office job and go to the gym at 6pm.
    I recomend dosing at 5pm, as dosing in the morning affects my focus too much, a heavy dose before bed leaves me waking up groggy.
    I was skeptical about placing an order as the website is very modest.
    Check out Trust Pilot for tonnes of good reviews

  34. Haven't seen the changes yet

    Posted by V on 19th Sep 2016

    Very early days I want to clarify firstly, however I'm yet to see or feel even the side effects i was expecting from this product; so far no significant increase in appetite or help with my sleep cycle, supplementing with 20-40mg a day. Will update if I do see any changes

  35. Best MK677 on the market

    Posted by Gamer on 26th Aug 2016

    I'v run 2 bottles for 12 weeks, dosing 20 mg everyday in the morning.
    -increased appetite
    -increased muscle mass
    -faster recovery
    -faster healing after injuries
    -better nutrition partitioning
    -increased metabolism
    -deeper, better sleep what comes with vivid dreams

    There is no suppression on it, no pct needed. My libido increased also while using it. Overall i felt myself very good on it and i highly recommend it to anyone who's looking for those HGH effects.

  36. Excellent but a bit pricey

    Posted by tl on 7th Aug 2016

    It does work. Seems to be high quality. Better than a liquid solution that I've tried recently. If it wasn't this expensive I would use it for longer periods of time.

  37. It is what its promissed

    Posted by Jp on 22nd Mar 2016

    Have not done it long time enough (20 mg) but there are enough research on mk-677 that says it works, and i like pills better than liquids.. Because suddenly you drop it sideways and everything is lost.. And much easier to take with your normal dose vitamins.. 10 mg pills is nice so you can take whatever dosage you need.. And the dna mk-677 i got before was good quality so now I just stick with it... I will run It with some cjc-dac to get extra hgh release but thats just me...

  38. Good product

    Posted by Burneymac on 27th Jan 2016

    Sarms good

  39. Great For Smooth Skin, Sleep and Lean Muscle

    Posted by Paul on 20th Aug 2015

    I have been using MK-677 for 4 months dosed at 3 caps in the AM 5 days on 2 off,

    I have noticed lean muscle mass gains whilst a decrease in body fat, improved skin quality, my skin has gone really smooth all over my body which is a sign that this product works great, sleep quality has improved greatly and overall recovery.

    5/5 a great product for boosting growth hormone levels and even better when used in combination with a product like huperzine a and prolactrone.

    I have also noticed a massive appetite increase which has made cutting slightly harder, nothing that i have not been able to fix with some Incinderine or Norcodrene.

    I will be having a break from this product for a few months and then continue running it again for my bulking season which i feel it will work well when used in combination with the new RAD Sarm.

    JW provide an excellent service and will be my main source for awesome exclusive supplements for the foreseeable future once again 10/10 on your awesome service and help every-time i need info on any of your products.
