What is PT-141 and what is BPC-157 + TB-500?
PT-141 is classified as Synthetic cyclic heptapeptide melanocortin agonist; BPC-157 + TB-500 as Co-formulated two-peptide research blend. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
PT-141
Synthetic cyclic heptapeptide melanocortin agonist
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.

Co-formulated two-peptide research blend
BPC-157 + TB-500 is a co-formulated research blend that combines two of the most frequently cited reference peptides in tissue-repair literature, BPC-157 / TB-500, in a single vial. BPC-157 is a synthetic pentadecapeptide derived from a partial sequence identified in human gastric juice; TB-500 is a synthetic 43-amino-acid peptide corresponding to an active fragment of thymosin beta-4, a naturally-occurring actin-binding protein.
full BPC-157 + TB-500 profile →Which research models is each compound studied in?
PT-141 sits in skin & glow research and BPC-157 + TB-500 in recovery & gut research, so their listed models largely do not intersect. The table lists 5 reported research applications for PT-141 and 5 for BPC-157 + TB-500. Rows are per compound, not equivalences.
| PT-141 — reported research applications | BPC-157 + TB-500 — reported research applications |
|---|---|
| Melanocortin-receptor (MC1R/MC3R/MC4R) binding research | Multi-compound tissue-repair research models |
| cAMP and G-protein-coupled receptor signaling assays | Cell-migration and wound-healing research |
