Growth Hormone and Growth Hormone-Releasing Peptides
Growth hormone is one molecule. The so-called "HGH peptides" are different molecules. They press other switches on cells, called receptors. They act one step before growth hormone, or alongside it. This hub explains what growth hormone is and how long it stays in the blood. It shows how the two main families of releasing peptides differ from it. It also says what Australian and sport records say, with every answer sourced and dated.

05- Are growth hormone peptides legal in Australia? Poisons Standard, TGA and WADA recordsWhat the October 2026 Poisons Standard (F2026L01327), the TGA and the WADA 2026 list record about somatropin, CJC-1295, ipamorelin, GHRP-2, GHRP-6, sermorelin and tesamorelin, with the date each record was checked. Records only; this is not legal advice.Updated 2026-10-16
- GHRH analogues vs ghrelin-receptor peptides: two inputs to growth hormone releaseGHRH analogues such as CJC-1295 and tesamorelin act on the GHRH receptor. Ghrelin-receptor peptides such as GHRP-6 and ipamorelin act on the ghrelin receptor. A comparison from papers, labels and the WADA 2026 list.Updated 2026-10-16
- HGH peptides vs HGH: are growth hormone-releasing peptides growth hormone?Growth hormone (HGH, somatropin) and growth hormone-releasing peptides are different molecules on different receptors. A comparison from FDA labels, papers and the WADA 2026 list, with the limits of each record.Updated 2026-10-16
- What is the half-life of growth hormone? Minutes in a vein, hours under the skinThe FDA labels give a half-life of 0.4 hours for intravenous Genotropin and 3.0 to 3.8 hours for somatropin given under the skin. The difference is slow absorption, not a second hormone.Updated 2026-10-16
- What is somatropin? Recombinant human growth hormone explained from the labelWhat somatropin is: recombinant human growth hormone of 191 amino acids, the receptor it binds, how it leads to IGF-1, and what the FDA labels and the Australian register say about it.Updated 2026-10-16
