Description
PT-141 10mg from Evolve Peptides is 10mg of PT-141 in a sealed glass vial. PT-141 is a melanocortin receptor agonist. It’s intended for lab research only.
PT-141 at a glance
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.
How PT-141 acts in the lab
PT-141 activates MC4R and MC3R in the hypothalamus, receptors involved in sexual motivation and arousal pathways. It acts on the brain, not on blood flow, which sets it apart from PDE5 inhibitors.
Chemically it’s Melanotan 2 with a free acid where Melanotan 2 has a C-terminal amide.

PT-141 10mg reconstitution and concentration
Concentration is just the amount in the vial divided by the water you add. With 10mg in this vial:
- 1ml of bacteriostatic water gives 10mg/ml
- 2ml of bacteriostatic water gives 5mg/ml
- 3ml of bacteriostatic water gives 3.33mg/ml
Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it.
Use sterile bacteriostatic water. Warm the sealed vial to room temperature first so no condensation gets in, add the water slowly along the glass wall, and swirl gently until it’s clear. Never shake.
Storage and shelf life
Store sealed vials in the fridge (2 to 8°C) or freezer (-20°C), away from light. Mixed solution goes back in the fridge and should be used within about 28 days.
