HGH 191AA — Research Guide
HGH 191AA is recombinant human growth hormone produced in a 191-amino-acid full-length sequence (somatropin). It is the canonical reference compound in growth-hormone-axis research and is studied alongside GHRH analogues (Tesamorelin) and growth-hormone-secretagogue peptides.

Chemistry & identity
HGH 191AA (CAS 12629-01-5, MW 22125.1 g/mol) is a 191-residue recombinant protein produced by bacterial expression. Per-batch HPLC + MS verification; identity confirmed against the theoretical mass.
Research applications
- GH-receptor signaling and JAK/STAT pathway studies
- IGF-1 axis research models
- Comparative pharmacology against GH-secretagogue peptides
- Recombinant-protein quality-control research
- Long protein PK and stability characterization
Stability & storage
Lyophilized HGH 191AA is stable at −20°C protected from light and moisture. As a recombinant protein, it benefits from gentle reconstitution to avoid aggregation; published research uses bacteriostatic water and immediate refrigeration with no vortexing.

FAQ
What does '191AA' mean?
The full 191-amino-acid sequence of human growth hormone (somatropin). Some recombinant GH preparations omit the N-terminal methionine (giving 192AA); 191AA matches the native human sequence.
HGH 191AA vs GH-secretagogues like Tesamorelin?
HGH 191AA is the GH protein itself. Tesamorelin is a GHRH analogue that, in published research, drives GH secretion through the pituitary. They sit on different points of the GH-axis research spectrum.
What's the in-solution stability?
Recombinant GH is generally stable for short-term refrigerated storage post-reconstitution. Avoid freeze-thaw cycles.
Is this for human use?
No. In-vitro research use only.
