About this compound

Kisspeptin and PT-141 are offered as two individual peptide research substances that are packed together for use in laboratory investigations. Research contained in the published scientific literature has looked at these compounds with regard to their molecular features, peptide chemistry, ligand–receptor interactions, and receptor-binding properties. In the case of kisspeptin, it has been studied in terms of its interaction with KISS1R/GPR54, and PT-141 has been examined for its binding to melanocortin receptors and the related molecular signalling mechanisms. Further laboratory studies have looked into structure–activity relationships, peptide–receptor interactions, and the biochemical behaviour of the substances under controlled experimental conditions. The materials are provided solely for use in laboratory, analytical, and educational research.

Questions researchers ask

Yes. The stack is supplied as two separate peptide vials. Both Kisspeptin and PT-141 are characterized in their Certificates of Analysis as white or almost white powders that conform to the listed product specifications.
