Aesthetic & Vitality

This category covers research compounds studied in melanocortin and neuroendocrine signaling, pathways distinct from the metabolic, recovery, and growth-hormone compounds elsewhere in the catalog.
The melanocortin family
The melanocortin system is a signaling network built around alpha-MSH and its family of receptors, studied across pigmentation, energy balance, inflammation, and central nervous system research. PT-141, also known as bremelanotide, is a synthetic cyclic peptide agonist within that family, concentrating on the MC3 and MC4 receptors most studied in central signaling. MT-2 is the related analogue from which it was developed. The tripeptide KPV comes from the same parent hormone, representing its final three residues, and is studied on the inflammation side of the family.
Neuroendocrine signaling
Kisspeptin-10 sits in the adjacent neuroendocrine research space, studied for its role upstream in hormonal signaling cascades. Oxytocin is the well-characterized nonapeptide with a long research history in social and physiological signaling.
Verification
Cyclic and modified peptides are harder analytical targets than simple linear sequences, which makes independent testing more valuable here rather than less. Every compound is analyzed for purity by HPLC and identity by mass spectrometry at an independent laboratory, with certificates published in our COA portal before you order. Our supplier vetting guide applies the same checks to us that it applies to anyone. All compounds are sold for laboratory research use only.
