ABOUT HGH 191AA
HGH 191AA (somatropin) is the full 191-amino-acid sequence of endogenous human growth hormone, produced via recombinant expression. It is the benchmark compound in GH research — studied for lean tissue accrual, fat metabolism, recovery capacity, skin and connective tissue quality, and sleep architecture. Where secretagogues stimulate the body's own pulse, 191AA is the direct reference standard. Every vial is third-party tested with batch documentation available.
Research highlights
- Identical 191aa sequence to endogenous GH
- The reference standard of GH research
- 10IU lyophilised vial
- Cold-chain packed, Australia-wide
HOW IT'S STUDIED
Recombinant somatropin identical to endogenous 191-amino-acid growth hormone — acts directly on GH receptors, driving IGF-1 production and anabolic signalling in research models.
Lyophilised: store at 2–8°C. Once reconstituted, refrigerate and use within 2–3 weeks. Do not freeze reconstituted solution.
Studied applications
- Lean tissue & body composition research
- Recovery capacity
- Skin & connective tissue quality
- Sleep architecture
