— About this compound
PT-141 (bremelanotide) is a cyclic heptapeptide analog of α-MSH that acts as a non-selective agonist at melanocortin receptors with preferential activity at MC3R and MC4R. The cyclic structure confers proteolytic stability relative to linear α-MSH analogs.
In contrast to peripheral PDE5-inhibitor mechanisms used by earlier sexual-medicine compounds, the bremelanotide mechanism is central — acting at hypothalamic melanocortin receptors. The compound has been investigated extensively in both preclinical and Phase 3 human research.
— Mechanism
Non-selective melanocortin receptor agonist with preferential activity at MC3R and MC4R in hypothalamic neuronal populations. Activation modulates downstream neuroendocrine pathways implicated in sexual response in preclinical models.
— How it’s made
Every Nexa batch follows the same documented path. Five steps, every one verifiable.
01
Sourcing
Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.
02
Compounding
Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.
03
Verification
Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every batch before it leaves the lab. The chromatogram is archived.
04
Release
No batch ships until an independent laboratory has returned its identity and purity results and the certificate is published in the COA library.
05
Dispatch
Sealed vials with a QR code on the label that opens the COA library. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.
