PT-141, or bremelanotide, is a cyclic heptapeptide metabolite of melanotan II that acts on central melanocortin receptors — principally MC4R — rather than peripheral vascular tissue.
Reference data researchers look up before ordering pt-141 (bremelanotide). Every lot ships with documentation matching the batch number printed on the vial.
Each pt-141 (bremelanotide) lot is released only after an independent purity panel. HPLC quantifies purity, LC-MS confirms molecular identity, and the lot-matched certificate is published so the number on your vial matches the report you download.
PT-141 (Bremelanotide) ships lyophilized. Reconstitute with bacteriostatic water containing 0.9% benzyl alcohol. The ratios below assume a standard U-100 insulin syringe.
PX1 Research synthesizes and fills pt-141 (bremelanotide) in a US cGMP-compliant facility rather than reselling imported material, so purity documentation traces back to the production lot. Multi-vial pricing steps down at 3, 5 and 10 vials, and subscription intervals are available on the product page.

Need solvent? Buy bacteriostatic water (10mL / 30mL)
No. PT-141 is a metabolite of melanotan II that lost the pigmentation-driving activity and retains central melanocortin signaling.
Primarily MC4R in the central nervous system.
Yes. Every pt-141 (bremelanotide) lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.
Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
