What is PT-141?
PT-141 (bremelanotide) is a cyclic seven-amino-acid peptide derived from melanotan II. It activates melanocortin receptors, mainly MC4R, in the brain.
An injectable form is FDA-approved as Vyleesi for hypoactive sexual desire disorder in premenopausal women.

Research on PT-141
The RECONNECT phase 3 trials, published in Obstetrics & Gynecology in 2019, were the basis for approval.
Earlier studies looked at it in men.
You can find the papers on PubMed. We don’t make claims beyond what that literature reports.
How to mix a PT-141 vial
The vial holds PT-141 as a dry, freeze-dried cake. To use it, dissolve it in bacteriostatic water, letting it run slowly down the side of the glass so it doesn’t hit the powder directly. Swirl or roll the vial until it’s clear. Shaking can damage peptides, so skip it.
The amount of water you add sets the concentration. For example, adding 2mL of bacteriostatic water to a 10mg vial gives 5mg per mL. Write the volume and the date on the label so anyone picking up the vial later knows what’s in it.
We sell bacteriostatic water in 30mL vials, and acetic acid solution for the few peptides that don’t dissolve well in water.
PT-141 quality and testing
Every batch of PT-141 is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storing your PT-141
Keep it in the fridge at 2 to 8°C and don’t freeze it. Once mixed, keep the vial in the fridge and use it within a few weeks. Unmixed vials keep much longer, so only reconstitute what you need. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
Common questions about the PT-141 peptide vial
Does PT-141 come with water to mix it?
No. The vial holds only the freeze-dried powder. Add bacteriostatic water to your order if you don’t already have some.
How long does mixed PT-141 last?
Kept in the fridge, most reconstituted peptides are good for a few weeks. Unmixed vials last much longer, especially in the fridge or freezer.
Is the PT-141 peptide vial in stock?
Yes. Every option on this page is in stock and ready to ship.
