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. 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.

  2. 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 !

  3. 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.

  4. 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.

  5. 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!!

  6. 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.

  7. 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!

  8. good product and very good service.

    Posted by YM on 14th Dec 2018

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

  9. 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.

  10. 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!!
