MK-677 (Ibutamoren) by Core Labs X: the “growth hormone SARM”

MK-677, also known as "Ibutamoren," is one of the best-known SARMs, even though it isn't actually a SARM. Unlike true SARMs (Selective Androgen Receptor Modulators), it doesn't stimulate androgen receptors, but rather promotes the secretion of growth hormone (HGH). MK-677 is therefore a growth hormone secretagogue—the only orally available one developed to date. It acts as a neurotransmitter and mimics the effects of the hormone ghrelin in the brain, causing the pituitary gland to release HGH and IGF-1 (Insulin-Like Growth Factor). This manifests itself in significantly accelerated muscle growth, increased bone density, and a reduction in body fat reserves.

What makes MK-677 from Core Labs X special?

As mentioned, MK-677 does not act on the androgen receptors – therefore it has no negative impact on endogenous testosterone production. Following MK-677 use (8 to 16 weeks are recommended), no post-cycle therapy is necessary. The usual daily doses in bodybuilding range from 10 mg to 30 mg per day. Since MK-677 has a half-life of around 24 hours, the entire daily dose can be taken all at once. To prevent water retention (water retention is one of the known side effects of ibutamoren), the MK-677 capsules from Core Labs X contain, among other things, the minerals magnesium and potassium , which ensure a balanced fluid balance.
