What is HGH?

HGH (Recombinant Human Growth Hormone (191 aa, somatropin)) is a 191-amino acid recombinant protein. Recombinant human growth hormone acting directly at the GH receptor (GHR) — bypasses the pituitary entirely with non-pulsatile pharmacokinetics. Stimulates hepatic IGF-1 production, anabolic signalling in muscle via IGF-1R, adipose lipolysis, and GH-induced insulin resistance at supraphysiological doses.

Research Applications

GH Receptor Biology

Direct GHR binding, JAK2-STAT5 signalling, receptor downregulation

IGF-1 Axis

Hepatic IGF-1 production, IGFBP regulation, GH→IGF-1 axis

Body Composition

Muscle anabolism, adipose lipolysis, nitrogen retention models

GH Deficiency Models

Hypopituitary and GH-deficient rodent restoration research

vs Secretagogues

Pulsatile (secretagogues) vs non-pulsatile (direct HGH) comparison
