Tanning & Libido Peptides
The tanning and libido category covers peptides studied for their effects on the melanocortin receptor system — the family of receptors (MC1R through MC5R) that govern pigmentation, melanogenesis, and related behavioural pathways. These compounds are used in preclinical and in-vitro research investigating melanocortin receptor pharmacology and the downstream effects of receptor agonism. Every batch is verified at HPLC Peps UK laboratory at >99% HPLC purity.
