Regular Price$117.99Sale Price$99.99

• Description

  Research-grade PT-141 (Bremelanotide) — 10mg lyophilized peptide supplied with a separate vial of sterile diluent (0.3% potassium sorbate). PT-141 is a cyclic heptapeptide melanocortin receptor agonist. 99%+ purity verified by an independent third-party lab via HPLC and mass spectrometry.

  PT-141, also known as Bremelanotide, is a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone and acts as an agonist at melanocortin receptors.

  Supplied with sterile water preserved with 0.3% potassium sorbate; no separate bacteriostatic water is needed.

• Frequently Asked Questions

  DO I NEED TO BUY BACTERIOSTATIC WATER SEPARATELY?

  No. Every nasal spray ships with its own diluent — sterile water preserved with 0.3% potassium sorbate, supplied with every spray. This differs from the lyophilized vials in our catalogue, which are reconstituted with bacteriostatic water sold separately.

  WHAT IS PT-141?

  PT-141, also called Bremelanotide, is a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone that acts as an agonist at melanocortin receptors. It is studied in research models for receptor subtype selectivity and downstream signalling.

  HOW SHOULD IT BE STORED AFTER RECONSTITUTION?

  Keep the bottle refrigerated at 2–8°C and protected from light both before and after reconstitution. Once reconstituted, use within an appropriate research timeframe — a peptide in solution has a materially shorter usable life than the sealed lyophilized material.

  HOW IS IT SHIPPED IN CANADA?

  Orders placed and paid before 3:00 PM ET 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.

  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.
