| Name | Somatropin (HGH) |
|---|---|
| Also known as | Recombinant human growth hormone, rhGH, Human growth hormone |

Overview
Somatropin is a laboratory-produced version of the 22 kDa human growth hormone. It is discussed in the literature in the context of growth-hormone deficiency and body-composition research. In many jurisdictions it is a prescription medicine, and non-medical use is a frequent topic of caution.
How it’s thought to work
- Binds the growth-hormone receptor to trigger intracellular signaling.
- Stimulates hepatic production of IGF-1, which mediates many downstream effects.
- Influences protein, lipid, and carbohydrate metabolism.
- Acts on growth plates and multiple tissues during development.
Researched uses
- Growth-hormone deficiency in clinical settings
- Body-composition and lean-mass research
- Recovery from certain catabolic states
- Metabolic studies of lipolysis and glucose handling
Commonly cited protocol
| Typical dose | Commonly cited around 1-3 IU per day in research contexts |
|---|---|
| Frequency | Typically once daily, often evening |
| Route | Subcutaneous injection (clinical) |
| Notes | Dosed in international units (IU); clinical dosing is individualized and supervised. |
Reconstitution
Supplied as a lyophilized powder reconstituted with the accompanying diluent or bacteriostatic water. Because it is dosed in IU rather than a fixed mg target, standard peptide unit math does not map cleanly; follow the product's IU-per-vial labeling.
Cautions
- Prescription medicine in many countries; non-medical use is generally restricted or prohibited.
- Associated in the literature with fluid retention, joint discomfort, and effects on glucose tolerance.
- Purity and potency vary widely in non-pharmaceutical sources.
- Not intended as medical advice; use only under qualified supervision.
