what is pt-141?
PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide analog of the melanocortin family, structurally related to alpha-melanocyte-stimulating hormone and to the earlier research analog Melanotan II. Verve supplies it as a high-purity research compound for laboratory melanocortin-receptor research.
In cellular research, PT-141 is used as a reference agonist for characterizing binding and downstream signaling at melanocortin receptors, principally MC1R, MC3R, and MC4R, including cAMP accumulation assays and receptor-selectivity profiling. Verve's PT-141 is manufactured in the United States, screened by HPLC to a 99%+ purity standard, and published with a batch-level certificate of analysis.
common research applications
PT-141 is supplied strictly for laboratory research use only. Reported research contexts include:
- Melanocortin-receptor (MC1R/MC3R/MC4R) binding research
- cAMP and G-protein-coupled receptor signaling assays
- Receptor-selectivity and structure–activity profiling
- MC1R and melanogenesis research models in cell culture
- Cyclic-peptide stability and conformation research
purity, testing & COA
Every batch of verve PT-141 is synthesized and vial-filled in the United States and screened by an independent, accredited laboratory for identity, purity, and contaminants, with analysis by HPLC and, where appropriate, mass spectrometry. Products are manufactured to a 99%+ purity standard where stated, and an endotoxin-tested option is available for many compounds.
That lab report is the certificate of analysis. Match the batch code printed on your vial to the row in our COA library and you're reading the exact report for the exact vial in your hand. Every order includes a free downloadable COA, damage protection in transit, and full US tracking. Orders placed Monday–Friday ship by 2pm CT, free over $100.
