MK 677 (Nutrobal)

Other Name(s): Nutrobal, Ibutamoren, Oratrope, Crescendo
Half Life: 24 hours

Produced by Reverse Pharmacology, MK 677 (commonly known as Nutrobal) is an orally administered growth hormone secretagogue that is designed to stimulate the pituitary gland to release growth hormone.

It was originally formulated to manage health problems like osteoporosis, obesity and muscle wasting, but MK 677 has been shown to promote an increase in lean body mass as well as a boost in IGF-1 serum concentration during clinical runs.

For this reason, it didn’t take people in the bodybuilding industry very long to start using it as a way to enhance their performance.


How MK 677 (Nutrobal) Works

Like most other SARMs, Nutrobal works by targeting specific androgen receptors and alters the way they function in the body.

As a result, this stimulates them in a way that can mimic the anabolic effects of steroids and prohormones. MK 677 (Nutrobal) is rather similar to peptides like Ipamorelin and GHRP-6, but you won’t experience any of the typical side effects.

This is why SARMS like MK 677 are considered as game changers in the world of fitness and in pharmaceutical science.

Moreover, here are the positive effects of MK 677 (Nutrobal) in terms of improving growth hormone pulse intensity:

  • Inhibits the signaling of somatostatin receptors
  • Slows down the activity of somastostatin in the system
  • Improves somatotroph signaling in growth hormone releasing hormones (GHRH)
  • Amplifies and increases the overall production and release of GHRH

Benefits of MK 677 (Nutrobal)

Aside from a dramatic change in your IGF-1 and growth hormone levels while on MK 677, you can experience many benefits from a cycle including:

  • a more rapid healing of ligaments, tendons, bones as well as old injuries
  • builds lean muscle mass and size gains
  • increases the oxidation of fat
  • and has even been shown to loosen tight skin after weight loss!

In Terms of Sleep:

Most users who have already tried taking MK 677 shared that they experienced better sleep while on this growth hormone secretagogue. They also had an increase in vivid dreaming in the process, which made going to bed much more satisfying and exciting from their perspective.

Possible Side Effects

Akin to other products that stimulate the elevated amounts of growth hormones in the body, MK 677 (Nutrobal) can cause a slight increase in appetite, temporary bouts of lethargy and numb hands.

Some claim it could lower GHIH levels, but that’s still to be determined.

Where to Buy MK 677 (Nutrobal) Online

Most of the most trusted distributors have halted their businesses after the ban of  SARMs.  They are, however, still available through a few distributors.

If you want to experiment for yourself and see the incredible power of a SARM like Nutrobal, you can order some online at many research labs across the country and Worldwide. has the highest quality SARMs available, including MK 677 for really cheap.

Also, you can purchase capsulated products such as KONG that include MK 677 and a stack of other SARMs.

Recommended Dosage

Studies have already been done on dosing the of MK 677 ranging from 10mg all the way to 50mg.

What they found is that while the HGH levels were NO HIGHER than at 50mg than those who took 10mg, it DID show an increase in IGF levels.

What this suggests is that for general fat burning and stamina, 10mg is sufficient enough to improve HGH levels and see results.

But if you want a little bit more of the muscle buildling effects, a higher IGF level will be effective and you might consider increasing your dosage to up to 50mg.

As a general guideline, most users suggest a sweet spot of about 25mg per day, which could increase IGF levels by as much as 80% during the first 30 days at 25mg.

Tip: Take it right before bed for maximum effect and some extra dreaming benefits.

Final Thoughts of MK 677

I think MK 677 is a SARM that you should go for based on four (4) key factors: ease of use, efficacy, minimal side effects and clinically proven results. With its ability to boost HGH levels, it’s almost as if you’re taking HGH itself.

If you’re still zeroing in on a SARM to go for, Nutrobal is definitely an option you should consider.

    Thanks so much for this article on mk 677 i can’t afford to run growth hormone and have been reading about mk 677 nutrobol as a HGH alternative. It sounds like mk 677 is the best hgh alternative by far.

    I was wondering if MK 677, LGD 4033 and Mk 2866 makes you sterile? My wife and I are trying to have kids…

    Thank you

      Not sterile but will cause some shutdown so as long as you use some PCT you should be fine

    I bought mk677, I take 1ml a day in the morning, but I noticed a quite disturbed sleep yet I had heard that it should not be taken just before bed to avoid disturbed sleep, you knew this problem?

    1. T says

      I heard of MK677 from a young fellow who mentioned he takes it for a short time when he wants to increase his lean mass. He looked liked he did not need it at the time and seemed knowledgeable and I asked what he read to gain his knowledge and said his dad is a doctor an his mom a pharmacist. He said natural growth hormone is active at night. That is why many who take HGH have bad results because taking it during the day disrupts the normal action which affects other hormone paths such as cortisol which is normally most active early in the morning. As it appears MK677 increases action of HGH and iGF-1, and one wants that to peak at night, then it would seem one would want to try MK677 sometime before sleep.

    I am on my 3rd week of the MK 677 cycle. I am doing this in camp as I work a 2 week in 2 week out 12 hr day schedule. I take 25mg 1 hr before bed but find it hard having to be taken on a empty stomach. At first I did notice the better sleep entering REM sooner rather then later as sleep becomes more necessary later in my work cycle. My strength is coming gradually noticing this in my bench press. I for 1 am liking the benefits of using MK 677. Is there a recommended cycle for this?
