MK-677 vs Ipamorelin
This one is a genuine fork, because the two are taken completely differently — a daily pill versus an injection — even though they nudge the same hormone.

How they differ
Route
MK-677 is oral — no needles, no reconstitution. Ipamorelin is injectable and has to be mixed from powder. That alone changes the logging workflow.
Duration & cadence
MK-677's long half-life supports once-daily dosing; ipamorelin is short-acting. A daily oral and a short-acting injectable produce very different 'in your system' curves.
Tracking implications
For MK-677, consistency is the whole game — a daily check-off with a reminder. For ipamorelin, site and timing matter. Same app, different logging emphasis.
Status
Both are research compounds, not approved for human use. Labeled as such in the library.
Tracking either one
Whichever you log, the workflow is the same in Stack: add it once, set the schedule, and let the app handle reminders, supply projection and an "in your system" curve from the half-life. Run both? Group them into one protocol you can pause together.
