Ibutamoren Nutrobal (MK 677)


I am excited to bring you a very interesting weapon, for your fitness arsenal which is fairly new in the world of bodybuilding, called Nutrobal or Ibutamoren (mk677).

Before I tell you about this compound I must first address some myths.  First, Nutrobal (mk677) is often wrongly advertised and written about as being a SARM (selective androgen receptor modulator). It is actually a growth hormone secretagogue and a selective agonist of the ghrelin receptor.  Second, it differs from growth hormone and growth hormone peptides, due to its selective nature and also because it does not need to be injected.


Nutrobal (mk677) is in development to boost hormone deficiencies, including growth hormone and IGF-1 (insulin-like growth factor1) in adults, the elderly, and children.  It was originally branded as Oratrope and is considered by the FDA as an investigational new drug.  For the past year, it has been officially in the preclinical stage of development. 

In the meantime athletes, bodybuilders, and even normal joe gym rats have used Nutrobal (mk677) to help them reach their various fitness goals.   Before I get into all the cool things it does, first let me explain how it works.

How it works

Nutrobal (mk677) mimics ghrelin in the body.  Ghrelin is an endogenous hormone which is naturally produced in our gastrointestinal tract and works as a neuropeptide within the central nervous system.  It is popularly known as a potent appetite increaser. 

But it doesn’t just do that, it also has a huge effect on how energy is dispersed in the body.  This means it will change the way the body metabolizes fat, help suppress obesity, and help reverse type 2 diabetes. 

Ibutamoren Nutrobal (mk677), as a whole, will increase growth hormone and insulin growth factor1 WITHOUT increasing other hormones like cortisol or estrogen.  Another cool thing it does is it will not suppress your existing testosterone or growth hormone.

Advantages over growth hormone or peptides

Ibutamoren Nutrobal (mk677) will actually ADD TO existing growth hormone.  This gives it a great advantage over exogenous growth hormone which will suppress you in that regard.  Also, the price of growth hormone is extremely expensive.  Even if you manage to find growth hormone that is reasonably priced there is a strong likelihood that it is generic from China, which means it is very underdosed or bunk.  The ironclad way to get real growth hormone is via an anti-aging clinic, however, the price will be in the thousands per year and you need a prescription.

Peptides that increase growth hormone are much cheaper than exogenously injected growth hormone.   However, like the latter, peptides are frequently faked or underdosed.  Plus you need to mix and inject them, and when you aren’t doing that you must take great care to keep them refrigerated or they will go bad.  And to make matters more complicated many times when they are constituted they will go bad since they are so sensitive to touch or movement.

With Ibutamoren Nutrobal (mk677) all you have to do is take it since it is available orally.  And you can store it in your closet for years without it going bad.

Athletic uses

So what are the benefits of using Nutrobal (mk677) in real-world terms?

Boost Appetite

Many guys suffer from poor appetite, and we all know if you want to grow you have to eat.  Ibutamoren Nutrobal (mk677) will boost your appetite pretty quickly after you start using it, and users report they are able to eat much more food without feeling satiated.


Now you might think that eating more food will result in fat gain right?  Well not in this case.  Remember what I wrote earlier about how Ibutamoren Nutrobal (mk677) changes the way our body metabolizes energy.  So the beauty part of it all is you can eat more food, and still cut body fat.  And those who do manage to eat in a caloric deficit will find themselves shedding body fat like crazy on this stuff.

Better Sleep

Yet another benefit is sleep and sleep quality.  Many of us live high paced, stressed lives.  That is, unfortunately, modern society and things will never change in our lifetimes.  Ibutamoren Nutrobal (mk677) will not only help you sleep, but you will sleep much harder.  Users report sleep improvements in the first month of using. In addition, they also say they wake up in the morning feeling rested.

The overall benefits of increased IGF-1 (insulin growth factor-1) and growth hormone will boost lean muscle mass, strength, wellness, and endurance. 

Ibutamoren Nutrobal (mk677) is great for ANY sport and all athletes.

SARMs Stacks

Using it Solo

When used solo Ibutamoren Nutrobal (mk677) should be used at 25-50mgs per day split dose AM/PM.

Where to buy

Ibutamoren has been getting cracked down hard in the past 2 years due to the government and credit card processors.   Many sources have either shut down or have tricked consumers by selling them bunk products.  For a legitimate source please check out our forums at evolutionary.org and elitefitness.com.
