PT-141 Research Overview
PT-141, also known as Bremelanotide, is a synthetic analog of α-MSH that activates melanocortin receptors (MC3R and MC4R) in the central nervous system. It is the only research peptide in its class FDA-approved (as Vyleesi) for hypoactive sexual desire disorder in premenopausal women.

Molecular formula C₅₀H₆₈N₁₄O₁₀, molecular weight 1025.17 g/mol, sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH. PT-141 binds MC4 receptors in the hypothalamus, triggering dopamine release in the medial preoptic area. Unlike PDE5 inhibitors which target blood flow, PT-141 acts on the central pathways that govern libido and arousal — making it of interest for research into neurologically-mediated sexual response. PT-141 is supplied as lyophilized powder and is classified in our catalog under melanocortin receptor agonist for melanocortin receptor agonist work. Recorded research categories for this compound include sexual response and libido research, melanocortin receptor pharmacology, central nervous system arousal studies, hypoactive sexual desire disorder research. Handling notes: store at -20°c (freezer), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for PT-141: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions
What is PT-141 used for in research?
PT-141 (Bremelanotide) is researched for its effects on sexual desire and arousal via central melanocortin receptor activation, in contrast to vascular-targeted compounds.
How is PT-141 different from Viagra?
PT-141 acts on the central nervous system (MC4R in the hypothalamus). Viagra/Cialis are PDE5 inhibitors that work on vascular blood flow. They target different stages of sexual response.
Is your PT-141 third-party tested?
Yes. Every vial ships with HPLC and Mass Spec verification at ≥99.2% purity and an itemized Certificate of Analysis.
What is PT-141 studied for?
PT-141 appears in laboratory research covering cns research, sexual function studies, neuroscience. All references describe in-vitro and preclinical study models only.
Does PT-141 include a Certificate of Analysis?
Yes. Each PT-141 lot ships with a batch-specific third-party Certificate of Analysis reporting 99.2% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.
What form does PT-141 arrive in?
PT-141 is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
