Ibutamoren Nutrobal (MK677)


Ibutamoren Nutrobal (MK677) is a selective agonist of the ghrelin receptor and growth hormone secretagogue, often miscategorized as a SARM (selective androgen receptor modulator).  Many of those in the fitness industry have chosen to roll with this compound vs. using growth hormone releasing peptides (GHRP’s) or human growth hormone due to cost and to avoid injecting themselves.


Ibutamoren Nutrobal (MK677) is currently being developed medically to fight growth hormone and insulin-like growth factor1 (IGF-1) deficiencies in people of all ages.  The FDA (food and drug administration) currently classifies it as an investigational drug and it is sitting at the preclinical stage awaiting the next step.

Even though it is not yet approved in the medical field and not yet being prescribed, it doesn’t mean that research companies haven’t come up with the idea to produce it to sell to those looking for performance enhancing.  Athletes of all abilities and even average joes have been trying it and have reported some really cool results.

Method of action

Appetite increase

One of the first things you will notice when using Ibutamoren Nutrobal (MK677) is higher appetite.  Don’t worry, this isn’t your imagination, but it is actually the compound mimicking ghrelin.  Ghrelin is a pretty awesome neuropeptide in our central nervous system (CNS), which our bodies produce in our stomachs, and it is classified also as a hormone.  So when you take Ibutamoren Nutrobal (MK677) and increase ghrelin, your hunger will go through the roof.  Users report waking up in the middle of the night starving for food!

No Fat Gains

Now before you close out your browser because you think appetite increase is a bad thing for your goals, you should think again, because Ibutamoren Nutrobal (MK677) also changes the way energy is spread around the body.  Fat becomes metabolized different, hence obesity is blocked from occurring, and we even see evidence that those who are on the verge of type 2 diabetes can have this issue reversed.  So even if you eat more, you won’t gain fat!

Not affecting estrogen or cortisol

The next way it works is by adding to your own bodies insulin growth factor-1 (IGF-1) and growth hormone.  So it won’t shut your hormones done at all like exogenously injected human growth hormone would.  It also does not increase estrogen, cortisol or other muscle eating hormones that we don’t need.

MK-677 treatment elicited a significant GH response, followed by increases in serum IGF-I and IGFBP-3, whereas effects on cortisol secretion were transient. Changes in body composition and energy expenditure were of an anabolic nature, with a sustained increase in FFM and a transient increase in BMR.

Ibutamoren Nutrobal (MK677) review

Why use instead of growth hormone?

The main reason you are better off using Ibutamoren Nutrobal (MK677) and not injecting growth hormone, is what I mentioned above, which is one will add to your hormones and the other shuts you down.

No Injections

But there are a couple more reasons you should take a look at it too.  The first is Ibutamoren Nutrobal (MK677) does not need to be mixed, refrigerated and injected, so you just take the capsules.


The second is the cost.  Good quality Human Growth hormone costs into the thousands, while Ibutamoren Nutrobal (MK677) costs a fraction of that.

Why use instead of peptides?

Once again the glaring reason you want to use Ibutamoren Nutrobal (MK677) instead of peptides to raise growth hormone is due to the mixing, storage, and injecting factor.  But also we have seen a troubling trend where peptide companies are selling underdosed or bunk products.  In fact, those in the industry estimate that almost 100% of the peptides being sold online are straight from China, and completely bunk or underdosed at best.  So stop wasting your money and just buy Ibutamoren Nutrobal (MK677), which can be stored for years without worry about it going rancid.

Fitness uses

Muscle Gains & Fat loss

Ibutamoren Nutrobal (MK677) is great for those who are bulking since it increases appetite so much, allowing you to up your macros and get bigger and stronger.  It also can be used to cut down body fat since it alters how our body metabolizes food. Users say they shred up even when keeping their diets the same.

Strength Gains

Those who weight train will love the faster recovery between workouts.  They also are impressed by the lean muscle mass gains and the mild strength gains they get.  Endurance athletes say they see a boost in their running times too.

Injury repair

Injury repair is seen with Ibutamoren Nutrobal (MK677) as well.  Try stacking it with N2jointrx and TS Krill Oil from N2bm and you will notice a tremendous difference in how your joints and soft tissues feel.  One user said all his aches and pains from years of weight training went away from using this stack for 3 months.

Non-fitness uses

Those that struggle with an appetite will get instant benefits from Ibutamoren Nutrobal (MK677) within the first week or two.  It also will help you sleep better and harder at night, great for insomniacs.

How to use Ibutamoren

Ibutamoren Nutrobal (MK677) should be used for at least 2-3 months at 12.5-50mgs per day.  With the average dosage of 25mgs.


It can most certainly be used solo. And you can dose it all in 1 sitting, although twice a day dosing is most ideal.  The half-life is only 6 hours.

SARM Stacks

For bulking stack it with 10mgs a day of RAD140 (Testolone).

For cutting stack it with 20mgs a day of GW501516 (Cardarine).

It also stacks well with every other SARM (selective androgen receptor modulator).

Anabolic Steroid Stacks

It is safe to also stack it with anabolic steroids. Whether you want to bulk, cut, gain strength, or gain lean muscle mass.  A cool stack you can try if you want to bodybuild is Ibutamoren Nutrobal (MK677) 25mgs per day + 500mgs per week Primobolan + 150mgs per week of Testosterone Enanthate.

Who shouldn’t use Nutrobal?

I do not recommend using Ibutamoren Nutrobal (MK677) if you are under 21 years old.  Also if you are a tested athlete you should not use it. Since that is considered cheating, and you will be possibly be tested for it.

Women and men are both safe to use it.  Those who are overweight or underweight can use it.  There are very few situations where it would not be okay.

Where to Buy MK677

Be very careful where you buy this compound because there are a lot of fakes being sold out there.  Ibutamoren Nutrobal (MK677) can be purchased at sarms1.com.
