Nutrobal (MK-677) is highly valued by bodybuilders because of its unique ability to increase both human growth hormone and IGF-1; these hormones have many uses and benefits in the body but the main one of concern for us is the potential to boost muscle growth.

Nutrobal (MK-677) (Ibutamoren) was originally created as a possible hormone replacement therapy drug, this means it was created from the ground up to specifically provide benefits to GH and IGF-1 and it does this without causing the nasty anabolics steroid side effects.

In addition to muscle growth, we can gain significant other benefits from MK-677, particularly regarding recovery, brain function and sleep quality. This makes it much more than just another muscle gainer.

MK-677 comes with clear scientific evidence that it can increase the production and release of an IGF-1 and GH and maintain these increases in the blood without bringing about a rise in stress hormones like cortisol which is a catabolic hormone.

Yet there is still no approval for MK-677 to be medically used for humans so it remains classed as an investigational drug and can only be purchased through research companies.
