HGH — human growth hormone, known generically as somatropin — is one of the most thoroughly characterized hormones in medicine. Produced by the pituitary gland, it drives growth in childhood and continues to regulate metabolism, body composition, and tissue repair throughout life.
What you’re reading about
“HGH” refers to recombinant human growth hormone, biologically identical to the hormone the body makes. It is a well-established, prescription-regulated therapeutic; this profile is educational background on the hormone’s biology and research — not guidance on use.
Mechanism
Growth hormone acts directly and through IGF-1 (insulin-like growth factor 1), which it prompts the liver to produce. Together they influence protein synthesis, fat metabolism, bone density, and cellular growth and repair.
Research applications
- Growth hormone deficiency and growth disorders.
- Body composition, metabolism, and the GH/IGF-1 axis.
- Tissue repair and recovery research.
Clinical outlook
Unlike most compounds in this library, growth hormone is already a fully approved therapeutic with a decades-deep clinical record, used medically for growth hormone deficiency and several other specific conditions. Because it is a potent, tightly regulated hormone, its study emphasizes controlled clinical settings — and research continues to map the GH/IGF-1 axis’s role in metabolism, aging, and recovery.
