HGH
Recombinant human growth hormone — a 191-amino-acid polypeptide studied across endocrine signaling models.
Mechanism
Recombinant somatropin binds the growth hormone receptor (GHR), activating JAK2/STAT5 signaling and downstream IGF-1 transcription in hepatocytes. Studied for effects on lipolysis, protein synthesis, and glucose handling in research models.
Discovery
Growth hormone was first isolated from pituitary extract in the 1950s. Recombinant DNA production began in 1981, replacing cadaver-derived material and enabling standardized research supply.
Research Status
Extensively characterized in the peer-reviewed literature across endocrine, metabolic, and body-composition research models. Clinically approved in several jurisdictions for defined indications; research-grade material is distinct from clinical product.
Quality Notes
Purity, aggregation state, and correct disulfide folding are the key quality axes. Ares research-grade HGH is third-party tested with batch-traceable Certificates of Analysis.
