What is the purity of PT-141?
PT-141 is supplied at a HPLC-tested purity of 99%+ (HPLC, third-party tested). Each batch is independently analysed and a Certificate of Analysis (COA) is available on request.
How should this product be stored?
Store the lyophilized vial refrigerated at 2–8 °C and protected from light. After reconstitution, keep refrigerated and use within 2–4 weeks. For long-term storage of unreconstituted vials, -20 °C is recommended.
Is a Certificate of Analysis (COA) available?
Yes. A batch-specific third-party COA (HPLC purity, mass spectrometry) is available for every lot. Send us the batch number on your vial and we email the COA the same working day.
How is shipping within the EU handled?
We ship discreetly from the Netherlands with PostNL / MyParcel. Free shipping on orders over €250. Most EU destinations arrive within 2–5 working days with track & trace.

Research Overview
PT-141 (Bremelanotide) is a cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH), studied as a non-selective agonist of melanocortin receptors, with particular research focus on MC3R and MC4R subtypes. Unlike earlier peptides in this class, it activates melanocortin receptors independent of the cAMP-adenylate cyclase pathway used by natural agonists. It is widely used in neuroendocrine research to investigate central nervous system pathways involved in energy homeostasis, appetite regulation, and sexual behavior circuits.
Primary Research Areas
Melanocortin receptor (MC3R/MC4R) pharmacology and selectivity studies
Central nervous system pathways in sexual behavior research
Energy homeostasis and appetite-regulation signaling models
Melanocortin system structure-activity relationship (SAR) research
