Chromatographic purity by analyte
About this graph
Recorded scalar results against the stated specification. Each row uses its own labeled scale; purity is detector-area purity, not active-material content.
Measured active content
About this graph
Calibrated active content, concentration or activity compared with the stated same-unit specification. Each row uses its own labeled scale; no conversion from chromatographic purity is made.
PT-141 10mg is a melanocortin receptor agonist (mc3r/mc4r selective) supplied by Apex Laboratory as a high-purity research peptide intended strictly for in-vitro laboratory research and development applications.
Compound Overview
PT-141 (Bremelanotide) is a cyclic heptapeptide metabolite of Melanotan II. It activates melanocortin receptors MC3R and MC4R with relative selectivity over MC1R. Research focuses on its central nervous system melanocortin signaling, particularly in hypothalamic pathways regulating sexual arousal and behavior.
Research Background & Published Literature
The branded clinical product Vyleesi is approved for hypoactive sexual desire disorder (HSDD) in adult women; Apex’s research-grade material is supplied for in-vitro research only. Published in Journal of Sexual Medicine and Journal of Urology. Research examines CNS melanocortin signaling as distinct from peripheral melanogenesis pathways.

Storage, Handling & Stability Guidelines
Store lyophilized material at -20°C for long-term stability. After reconstitution with sterile diluent, refrigerate at 2–8°C and minimize freeze-thaw cycles by aliquoting working volumes according to your standard operating procedures.
- Minimize time at ambient temperature during handling to preserve compound integrity.
- Avoid moisture exposure by resealing vials promptly after each withdrawal.
- Use appropriate personal protective equipment and follow your institution’s chemical safety protocols at all times.
- Label all aliquots with the compound name, concentration, date of reconstitution, and operator initials for complete traceability.
Quality Assurance & Analytical Verification
Apex Laboratory applies a dual-verification quality protocol to every batch before it enters inventory. Each lot undergoes High-Performance Liquid Chromatography (HPLC) to confirm chromatographic purity and Mass Spectrometry (MS) to verify molecular identity and molecular weight. This two-step analytical process ensures that the material you receive meets our ≥99% purity standard with confirmed molecular integrity. Certificates of Analysis documenting these results are available in the batch verification panel on this page and in the COA library for your internal quality records.
