PT-141 Reconstitution Calculator
PT-141 is a melanocortin-receptor agonist peptide, a metabolite of Melanotan 2. It comes lyophilised, and the concentration you end up with is set by the water you add. This calculator includes 10 mg as input presets for PT-141. It is also recorded as Bremelanotide. Its reference molecular weight is approximately 1025.2 Da. Confirm the exact ingredient, formulation, and vial amount from the product label before entering numbers.

A worked PT-141 arithmetic example
Arithmetic illustration, not a recommended amount: a 10 mg PT-141 vial entered with 1 mL gives 10,000 mcg/mL. An entered 400 mcg value then returns 0.04 mL, 4 U-100 units, and 25 calculated portions.
Change any input above and the concentration, units, and doses update for your own vial.
Frequently asked questions
What does the PT-141 calculator calculate?
A 10 mg PT-141 vial contains 10,000 mcg. The calculator divides that amount by the liquid volume you enter, then converts the resulting volume to the selected syringe scale. Product preparation and treatment instructions must come from the product label or a qualified professional.
Which PT-141 vial amount should I enter?
This page offers 10 mg as PT-141 calculator presets. Use the exact amount printed on the product label; the preset is only an arithmetic starting value.
What is the molecular weight of PT-141?
PT-141 weighs roughly 1025.2 daltons. That figure does not change PT-141 syringe math — only the concentration you mix does.
