The study from pmc shows that daily oral mk‑677 over 8 weeks raised gh and igf‑i levels in healthy older adults to levels comparable to younger adults. Body composition data indicated a modest gain in fat‑free mass of about 1.1 kg versus a slight loss with placebo, and no serious adverse events were reported.

I find the numbers plausible but a bit optimistic. The 1‑kg lift could be swallowed by routine training gains or a few days’ better recovery. The paper also downplays the glucose changes that other trials flag; i’ve seen patients report a bit more appetite and a spurt in blood sugar with mk‑677. My own stack uses a lower dose, and i focus on verifying any metabolic shifts with bloodwork before going higher.

Question for the group: what’s your experience measuring glucose or insulin sensitivity after starting mk‑677, and do you think the body‑composition gains justify the mild hormonal shifts seen?
