Description
The PT-141 10mg 3 pack from Oath Peptides gets you 3 vials of PT-141 10mg for $135, or $45 a vial. PT-141 is bremelanotide, a cyclic melanocortin peptide (CAS 189691-06-3) supplied as freeze-dried powder.

What is PT-141?
PT-141, also called bremelanotide, is a synthetic cyclic heptapeptide in the melanocortin family. It was developed from Melanotan 2 and first described in the early 2000s. Its formula is C50H68N14O10 and it weighs 1,025.2 g/mol.
A lactam bridge between two side chains locks it into a ring. That’s common in melanocortin peptides. Compared with Melanotan 2, PT-141 doesn’t have the linear N-terminal extension, so it’s a smaller, fully cyclized piece.

What researchers study PT-141 for
PT-141 acts on melanocortin receptors (MC1R through MC5R) and was studied in clinical trials before a drug version was approved. The peptide we sell is research grade and for lab use only. See NIH PubChem.
How to store PT-141
Refrigerate at 36 to 46 °F (2 to 8 °C). It dissolves readily in water. Keep it cold once mixed.
Most labs reconstitute with Research Water, which is sterile-filtered water with 0.9% benzyl alcohol.
When it’s time to reconstitute, let the vial come to room temperature first. Add the solvent slowly down the inside wall of the vial so it doesn’t hit the powder directly, then swirl gently until the liquid is clear. Don’t shake it. Write the date on the label so you know how long it’s been mixed.
