Product Overview
PT-141 is a melanocortin-pathway research peptide studied for its relevance to neuroendocrine signalling, receptor-interaction modelling and comparative analysis of MC3R/MC4R biochemical pathways. This lyophilized 50 mg peptide supports controlled laboratory evaluation of purity identity and mechanistic response behaviour.

Peptide Overview
Between 2010 and 2025 PT-141 has been investigated across neuroendocrine signalling models due to its pathway specificity, stable structural profile and clear receptor-mediated behaviour. Its analytical consistency enables reproducible in-vitro modelling of melanocortin-system mechanisms.

Historical Background and Scientific Context
Melanocortin-related peptides became a significant scientific focus from 2014 onward as laboratories examined their involvement in central signalling pathways, neural-interaction models and receptor-agonist mechanisms. PT-141 emerged as a key analogue for evaluating pathway selectivity and biochemical stability.
