PT-141 (Bremelanotide) is a melanocortin receptor agonist (MW 1,025.2 Da), the same molecule as the FDA-approved drug Vyleesi. Research-grade material is supplied as a lyophilized powder for laboratory use.
What to Look for When Sourcing PT-141
Require a third-party COA (HPLC and mass spectrometry) confirming ≥98% purity and the 1,025.2 Da molecular weight. Verify the vendor is not marketing research material as the clinical Vyleesi product.
Typical Price Range
Research-grade PT-141 typically costs about $35–$55 per vial.
Storage and Handling
Store lyophilized PT-141 at 2–8°C. Once reconstituted, refrigerate and use within the vendor's stated stability window.
Red Flags to Avoid
Missing COAs, claims that research material is FDA-approved Vyleesi, prices far below market, and human-use claims.
