MK-677

Community Q&A

How long does MK-677 stay in your system?

Community accounts point to a 24-hour half-life, consistent with once-daily dosing producing stable overnight GH and IGF-1 elevation. The most noticeable effects — hunger and water retention — typically fade within 2–3 days of stopping. Discussions about drug testing reference detection windows of several days to weeks depending on the assay, though most of these are anecdotal rather than confirmed by lab results.

Does MK-677 cause water retention?

Water retention appears in the majority of early MK-677 accounts and is cited as the most common initial side effect. Community reports describe puffiness around the face and extremities, most pronounced in the first 4–8 weeks. A subset of accounts describe it resolving at stable dosing; others report it persists for the duration of use. Dropping from a loading dose to a lower maintenance dose is the most commonly described workaround.

When is the best time to take MK-677?

Community consensus strongly favours pre-bed dosing. The reasoning given: MK-677 amplifies the natural overnight GH pulse, and hunger — the most inconvenient side effect — is easier to ignore while asleep. Morning dosing accounts exist but consistently report greater disruption from appetite stimulation throughout the day. Some accounts describe splitting the dose (morning + evening) to moderate hunger while maintaining coverage.
