Description
PT-141 10mg is a 10mg vial of PT-141, a melanocortin receptor agonist, supplied by Blue Sky Peptide as freeze-dried powder. This batch tested at 99.63% purity. It’s for in-vitro and lab research only.
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.
How PT-141 works
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 vs related compounds
Labs choosing PT-141 10mg usually weigh it against a few close relatives. PT-141 is a melanocortin agonist derived from Melanotan II, acting on MC4 receptors in the brain, while:
- Oxytocin is the nine-amino-acid hormone behind labor, milk release and social bonding
- Triptorelin is a long-acting GnRH agonist that first stimulates, then shuts down, LH and FSH
These three act on separate hormone systems in the brain: melanocortin, oxytocin and GnRH. See them all on our hormone peptides page.
PT-141 10mg reconstitution and concentration
Concentration is the amount in the vial divided by the liquid you add. With 10mg in this vial:
- 1mL of water gives 10mg/mL
- 2mL of water gives 5mg/mL
- 3mL of water gives 3.33mg/mL
Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.
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 it.
How to store PT-141 10mg
The dry powder keeps best cold. A freezer at -20°C is ideal for long-term storage, and a fridge works for a few weeks. After reconstitution, store it in the fridge and finish it within roughly four weeks.
A 10-slot vial case keeps open and sealed vials upright and apart, which makes the fridge shelf a lot easier to manage. For transport, the Blue Sky hard storage box is the sturdier option.
PT-141 10mg purity and testing
Purity for this batch of PT-141 10mg came back at 99.63% by HPLC and mass spectrometry. That’s the figure for the batch currently in stock.
Every vial is labeled with the compound, the amount and the batch. If your lab keeps paperwork on file, email us the batch number from the label and we’ll send the certificate of analysis for it.
Keep the batch number with your records. It’s the quickest way to match a vial to its paperwork later.
