PT-141 reconstitution calculator
bremelanotide - approved as Vyleesi®
PT-141 (bremelanotide) is a melanocortin-receptor agonist - one of the few gray-market peptides with an actual FDA-approved sibling. The approved product is a fixed-dose autoinjector; vial forms circulate through men's clinics and research sellers, where the conversion math (and the blood-pressure contraindications) get lost.
Enter vial size, water volume, and the dose your provider gave you.
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 PT-141 the same as Vyleesi?
Same molecule (bremelanotide), different products. Vyleesi is an FDA-approved fixed-dose (1.75 mg) autoinjector for premenopausal women with HSDD. Vial-form PT-141 sold online or compounded for other uses is not an approved product.
How many units is 1 mg of PT-141?
From a 10 mg vial reconstituted with 2 ml (5 mg/ml), 1 mg = 0.2 ml = 20 units. With 3 ml of water (3.33 mg/ml) the same 1 mg is 30 units. Compute from your actual vial and water volume - never copy someone else's unit count.
What should I know about PT-141 safety?
The approved label for bremelanotide carries warnings about transient blood-pressure increases (it is not recommended for people with uncontrolled hypertension or cardiovascular disease), plus common nausea and flushing. Those warnings apply to the molecule, not just the brand.
