● PT-141Melanocortin peptide

PT-141 price comparison

PT-141 (bremelanotide) is a synthetic cyclic heptapeptide and melanocortin receptor agonist derived from the peptide Melanotan II, studied in laboratory and preclinical models for its activity at melanocortin receptors such as MC3R and MC4R. It is supplied as a research-use-only material and is not intended for human or veterinary use. This index tracks per-milligram pricing for PT-141 across research-chemical (RUO) vendors so researchers can compare current listings.

▸ Why compare $/mg for PT-141?

Per-mg prices vary because vendors sell PT-141 in different vial sizes, synthesis batches, and stated purity grades, and because packaging, lyophilization, and shipping overhead get distributed differently across small versus bulk quantities. Comparing normalized $/mg alongside a current COA lets a researcher weigh cost against documented identity and purity rather than headline vial price alone.

▸ Reading the COA

For PT-141, confirm identity by mass spectrometry against the expected monoisotopic mass (roughly 1024–1025 Da for the free peptide, molecular formula C50H68N14O10) and verify HPLC purity is reported, with many research buyers treating >=98% as a reasonable threshold. Check that the COA is lot-matched to the vial you receive and dated. Common flags on a melanocortin peptide like this include truncated or deletion sequences and acetate/TFA counter-ion content, so scan for reported related-substance peaks and residual-solvent notes rather than accepting a purity number in isolation.

▸ FAQ

What storage conditions do vendors typically state for lyophilized PT-141 as a research material?
As a lyophilized (freeze-dried) powder, PT-141 is generally described as most stable when kept cold and dry, and vendors commonly specify storage at -20C protected from light and moisture. This is general storage information for the research material and is not use or handling guidance. Always defer to the specific storage conditions and stability window printed on the vendor's COA or product page.
What is a COA and what should I check for on one for PT-141?
A COA (Certificate of Analysis) is the batch-specific document a vendor issues to characterize a given lot of material. For PT-141, check that it identifies the peptide by mass spectrometry against the expected mass, reports HPLC purity with a chromatogram, lists the lot number, and matches the vial you received. It documents identity and purity of the compound; it is not a statement about any outcome or suitability for use.
Why do per-mg prices for PT-141 differ so much between vendors?
Differences usually trace to vial size (bulk lots lower the $/mg), the synthesis batch and stated purity grade, and how fixed costs like peptide synthesis, lyophilization, QC testing, and cold shipping are amortized across the quantity sold. Two listings can also differ because one includes a current lot-matched COA and third-party verification while another does not, which affects the effective value of the material.
