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
Diamond and colleagues conducted a preliminary placebo-controlled study of intranasal bremelanotide in premenopausal women with sexual arousal disorder. Physiological and subjective outcomes were assessed separately. This early clinical formulation is distinct from the research-use PT-141 material listed here.
Researchers interested in the published literature surrounding this compound can explore the following peer-reviewed resources for additional context on its mechanism of action, signaling pathways, and experimental applications in controlled laboratory settings:

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
Review the tests recorded for the applicable configuration and lot. The published Apex Laboratory record identifies the issuer, methods, results, units and acceptance criteria. A public configuration record does not by itself identify the lot currently shipping or establish independent accreditation.
Frequently Asked Questions
What is the primary research application of this compound?
This compound is classified as a melanocortin receptor agonist (mc3r/mc4r selective) and is used in laboratory settings to study related signaling pathways and biological mechanisms in controlled in-vitro experiments.
What storage conditions are recommended?
