How Long Does Melanotan I Last? Half-Life & Dosing Frequency
Melanotan I has a reported half-life of ~30-50 minutes. This page explains what that means for how long Melanotan I stays active, how quickly it clears the body, and how often it is dosed in research.
What Is Melanotan I'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 I, research reports a half-life of ~30-50 minutes. A synthetic MSH analog that provides sun-free tanning and UV protection.
How Long Does Melanotan I Stay in Your System?
A compound is generally considered mostly cleared after about five half-lives. With a half-life of ~30-50 minutes, Melanotan I is largely cleared after roughly 250 minutes. Individual metabolism, dose, and dosing frequency can shift this estimate.
What This Means for Dosing Frequency
Research protocols commonly use Melanotan I Every other day during loading (Any time of day). 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.
