How Long Does Melanotan II Last? Half-Life & Dosing Frequency
Melanotan II has a reported half-life of ~1 hour. This page explains what that means for how long Melanotan II stays active, how quickly it clears the body, and how often it is dosed in research.
What Is Melanotan II's Half-Life?
The half-life of a compound is the time it takes for the amount in the body to fall to half its original level. For Melanotan II, research reports a half-life of ~1 hour. A synthetic analog of alpha-melanocyte stimulating hormone for tanning and libido.
How Long Does Melanotan II Stay in Your System?
A compound is generally considered mostly cleared after about five half-lives. With a half-life of ~1 hour, Melanotan II is largely cleared after roughly 5 hours. Individual metabolism, dose, and dosing frequency can shift this estimate.
What This Means for Dosing Frequency
Research protocols commonly use Melanotan II Daily during loading, 1-2x weekly maintenance (Evening preferred (may cause flushing/nausea)). Dosing frequency is generally matched to the half-life and to how long the compound's effects last — peptides with shorter half-lives are often dosed more frequently, while longer-acting compounds may be dosed less often.
