— About this compound
Tesamorelin is a synthetic 44-amino-acid analog of human GHRH carrying a trans-3-hexenoic acid moiety at the N-terminus. This modification stabilizes the peptide against dipeptidyl peptidase IV (DPP-IV) cleavage, substantially extending plasma half-life relative to native GHRH and to sermorelin.
The compound is the most clinically validated GHRH analog in research literature, having been studied in multiple multicenter randomized trials in HIV-associated lipodystrophy and, more recently, NAFLD.
— Mechanism
Selective agonist at pituitary GHRH receptors. The trans-hexenoic acid modification confers DPP-IV resistance, producing longer duration of GHRH-receptor activation per dose. Downstream effects are mediated by pulsatile GH release and consequent IGF-1 generation.
— 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.
