PT-141 (Bremelanotide) — 10mg

Price$64.99

• Description

  PT-141, also known as bremelanotide, is a cyclic analog of the melanocortin peptide Melanotan II, developed as a non-selective agonist at melanocortin receptors with particular activity at MC4R and MC1R. The lactam bridge between the Asp and Lys residues constrains the peptide into its bioactive conformation. It is supplied as a lyophilized powder and ships from Ontario, Canada.

• Frequently Asked Questions

  WHAT IS PT-141?

  PT-141 (bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist, structurally a metabolite-derived analog of Melanotan II with its activity concentrated at the MC3R and MC4R subtypes.

  WHAT IS THIS VIAL RECONSTITUTED WITH?

  Bacteriostatic water, which is sold separately in our catalogue. The lyophilized powder is stable as shipped; once in solution its usable life shortens considerably, which is why it ships dry.

  HOW SHOULD IT BE STORED?

  Sealed and lyophilized, store at 2–8°C away from light; for long-term storage, −20°C is better. After reconstitution keep it refrigerated at 2–8°C and use it within an appropriate research timeframe — a peptide in solution has a materially shorter usable life than sealed lyophilized material.

  IS THE COA VERIFIABLE?

  Yes. Every batch is independently lab-tested with a unique report key you can confirm independently — see our guide on how to verify a lab report key.

  HOW FAST DOES IT SHIP IN CANADA?

  Orders placed and paid before 3:00 PM EST ship the same business day via Canada Post Xpresspost with full tracking. Shipping is domestic from within Canada, so there are no customs delays or border holds.
