Melanotan II reconstitution calculator
MT-2 · tanning peptide
Melanotan II is an α-MSH analog that darkens skin pigmentation and was the chemical parent of bremelanotide (PT-141). It is the peptide with the worst regulator-to-marketing ratio: openly sold for tanning while multiple national health agencies have published warnings, including case reports of atypical moles and melanoma diagnosed after use.

This tool converts the numbers you enter (dose ÷ concentration = volume). It never suggests a dose. The FDA has documented hospitalizations caused by mg / ml / unit conversion errors with vial-and-syringe products - if the readout surprises you, stop and verify with your prescriber or pharmacist.
Questions people actually search
Is Melanotan II safe?
It has the worst documented risk signal of the popular peptides: health agencies in several countries have warned against it, citing case reports of new atypical moles and melanomas after use, plus reliable nausea, flushing, spontaneous erections, and darkening of existing moles. No controlled human safety program exists.
Is Melanotan II the same as PT-141?
They're related - bremelanotide (PT-141) is a metabolite of Melanotan II that was developed into an actual FDA-approved drug for a sexual-desire indication. MT-2 itself was never developed to approval; it survives purely as a gray-market tanning product.
Why do MT-2 doses matter so much?
Amounts discussed online are in the hundreds of mcg, and the compound's effects (nausea, blood-pressure changes) are strongly dose-related. A mcg/mg mix-up on a 10 mg vial is a 1,000× error - exactly what this calculator exists to catch.
