Should retatrutide be cycled?
Studies in people do not establish an on and off schedule for retatrutide. It is still experimental. Its large final-stage studies gave it without breaks, the same way the approved GLP-1 drugs it is related to are used, not as a cycle. The schedules passed around online that stop and restart it are unverified. This site does not invent a schedule. Full detail at /cycling.
