Hepatotoxicity induced by MK-677
Era Cobani et al. BMJ Case Rep. 2025.
Abstract
MK-677, a growth hormone secretagogue, is gaining popularity among performance-enhancing supplements. While its side effects include oedema, increased appetite and muscle pain, reports of hepatotoxicity are scarce. Here we present the case of an otherwise healthy man in his early 30s, who developed transaminitis after consuming MK-677 for 2 months before presentation. Liver function tests eventually returned to normal limits after stopping the supplement.
