TL;DR
MK-677 is a GH secretagogue, not a SARM; different mechanisms.
Full Post:
## Is MK-677 a SARM? Short answer: Nope, MK-677 (Ibutamoren) is not a SARM. ### What it is: - Type: Growth hormone secretagogue - How it works: Agonizes ghrelin receptors, stimulating the pituitary gland to release growth hormone (GH) and IGF-1. - Administration: Oral, no injections needed. ### Why the confusion with SARMs? - Often sold together with SARMs. - Frequently used in body recomposition stacks. - Classified as a research chemical. - Misunderstanding in the fitness community ("bro science"). ### Key Differences: | MK-677 | SARMs | |----------------------|-----------------------| | Boosts GH/IGF-1 | Stimulates androgen receptors | | Non-steroidal | Steroidal anabolic compounds | | Not suppressive (usually) | Can suppress testosterone | | Increases appetite, water retention | Strength & lean mass effects | ### TL;DR: MK-677 is a GH secretagogue, not a SARM. It’s orally bioavailable and used in long-term cycles (4–6 months). It doesn’t bind to androgen receptors—totally different mechanism. For research purposes only. Not approved for human consumption.
