HGH 191AA (Somatropin) — Recombinant Human Growth Hormone Research Compound

Catalog ID: HGH | CAS: 12629-01-5 | Sequence: 191 amino acids (identical to native human growth hormone)

Compound Overview

HGH 191AA, also known as Somatropin, is a recombinant form of human growth hormone composed of 191 amino acids identical in sequence to endogenous pituitary-derived GH.
It is produced via recombinant DNA technology and used in research to study **growth factor receptor signaling**, **protein synthesis**, and **metabolic regulation** in mammalian cell models.
For laboratory research use only — not for human consumption or therapeutic application.

Research Context

Somatropin (HGH 191AA) is used in in vitro and in vivo models examining **growth factor receptor interactions (GHR/IGF-1R)**, **cell proliferation**, and **protein synthesis**.
Studies explore its regulatory role in **JAK-STAT and MAPK signaling cascades**, **metabolic adaptation**, and **peptide-based anabolic mechanisms**.
Comparative research often includes **IGF-1 LR3**, **CJC-1295**, and **GHRP peptides**, forming a key foundation for **endocrine growth factor pathway modeling**.
