MK-777, also sold as Acetamoren, is a research-chemical product name whose identity is not established in any public scientific record: there is no published structure, no pharmacology paper, no animal study, no pharmacokinetics and no registered trial under either designation, and PubChem holds no compound record for either name. Vendors describe it as an orally active growth hormone secretagogue acting at the ghrelin receptor GHS-R1a and present it as a successor to ibutamoren, the compound Merck developed as MK-0677 and which this site covers separately; that description is borrowed from ibutamoren's pharmacology, not measured for this material. Some sellers publish CAS 950841-87-9 for it, which resolves in PubChem to N-acetyl ibutamorelin, an acetylated ibutamoren derivative that itself has no published pharmacology, but no independent source links that structure to the material actually shipped, so this page states the identity as unestablished rather than guessing at a formula.
