What is PT-141?

PT-141 (Bremelanotide — MC4R-preferring melanocortin agonist) is a 7-amino acid cyclic peptide (Melanotan II metabolite). Melanotan II metabolite with preferential MC4R activity over MC1R. Lacks the cyclic structure producing significant tanning (MC1R) activation, making it more selective for CNS MC4R pathways involved in sexual function and appetite. Acts centrally rather than via vascular mechanisms.

Research Applications

MC4R Selective Pharmacology

Preferential MC4R vs MT-II (MC1R+MC4R) — receptor selectivity research

Sexual Function Biology

Hypothalamic MC4R-mediated arousal pathways

Appetite via MC4R

Central appetite modulation, energy balance studies

CNS Melanocortin

Central vs peripheral melanocortin receptor biology

vs Melanotan II

Receptor selectivity comparison — identical structure, different profile

Frequently Asked Questions

How do I reconstitute PT-141?
Add 1–2mL bacteriostatic water to the lyophilized PT-141 (Bremelanotide) vial. Swirl gently until dissolved to a clear, colourless solution. PT-141 dissolves readily as a cyclic heptapeptide analogue.
How should PT-141 be stored?
Store lyophilized at −20°C. Reconstituted: 2–8°C for up to 28 days. Protect from light. PT-141 is a cyclic lactam-bridged peptide with good structural stability.
What purity is Vesta PT-141 and how is it verified?
Vesta PT-141 (Bremelanotide) is ≥99% HPLC pure with MS-confirmed cyclic heptapeptide identity on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
