Peptide Intelligence
What is the half-life of MK-677?
MK-677 (Ibutamoren) has a half-life of approximately 24 hours, allowing for convenient once-daily oral dosing. Unlike injectable GHRPs, it does not require reconstitution and achieves consistent IGF-1 elevation with daily use.
Does MK-677 suppress natural GH production?
MK-677 stimulates pulsatile GH release at the pituitary's own ghrelin receptors rather than suppressing it. Prolonged use may cause mild pituitary desensitization. It does not suppress the hypothalamic-pituitary axis the way exogenous GH does.
What are common side effects of MK-677 in research?
The most commonly reported effects include increased appetite, water retention, and elevated fasting blood glucose. Some research subjects report vivid dreams from GH-induced sleep deepening. Blood glucose monitoring is advisable during extended MK-677 use.
