Short answer
What is HGH?
HGH (somatropin) is a recombinant form of human pituitary growth hormone, a single-chain protein of 191 amino acids.
It also appears in the literature as somatropin, somatotropin (human), human growth hormone, rhGH, GH1.
What is in each HGH vial?
| STRENGTH | FORM | PRICE | CERTIFICATE |
|---|---|---|---|
| 15IU | Lyophilised powder | A$89 | Pending |
What has research on HGH examined?
Growth hormone has been studied extensively in human clinical trials, including controlled trials in adults with growth hormone deficiency and trials in healthy older adults. Systematic reviews have examined controlled studies of growth hormone administration in healthy elderly people and in athletic-performance settings.
The table lists primary sources by year and model. Findings describe the study subjects, not this research vial.
| STUDY | YEAR | MODEL | PMID |
|---|---|---|---|
| Effects of human growth hormone in men over 60 years old | 1990 | human | 2355952 |
| Systematic review: the safety and efficacy of growth hormone in the healthy elderly | 2007 | review | 17227934 |
| Systematic review: the effects of growth hormone on athletic performance | 2008 | review | 18347346 |
| Evaluation and treatment of adult growth hormone deficiency: an Endocrine Society clinical practice guideline | 2011 | review | 21602453 |
What adverse events have studies of HGH reported?
Two systematic reviews of randomised trials looked at growth hormone in healthy adults. In older adults, recipients more often had soft-tissue oedema, joint pain, carpal tunnel syndrome and gynaecomastia, and were somewhat more likely to develop diabetes or impaired fasting glucose (PMID 17227934). In young, fit adults, oedema and fatigue were more frequent (PMID 18347346).
These findings describe the people or animals in each study. The sources list gives every PubMed record.
How do you reconstitute and store HGH?
Store the sealed vial frozen (about -20 degrees Celsius), dry and away from light until it is reconstituted.
After reconstitution with a sterile solvent, keep the solution at 2 to 8 degrees Celsius and avoid repeated freezing and thawing. Record the solvent, volume and date on the vial label.
BAC Water is the usual laboratory solvent. Dilute acetic acid is an alternative for peptides that dissolve poorly in water. The reconstitution guide and storage guide cover laboratory handling.
| STATE | TEMPERATURE | NOTES |
|---|---|---|
| Sealed vial | -20 °C | Dry and dark. Keeps to the label date. |
| Reconstituted | 2 to 8 °C | Sterile technique. Avoid repeat freeze and thaw. |
| In transit | Cold pack | Refrigerate or freeze on arrival. |
Is HGH legal to buy in Australia?
Somatropin (human growth hormone) is listed in Schedule 4 of the Poisons Standard (prescription only). It is also listed in Appendix D clause 5, which makes possession without authority an offence. Source: the June 2026 Poisons Standard instrument (F2026L00633).
WADA's 2026 Prohibited List prohibits HGH at all times, under class S2 Peptide hormones, growth factors, related substances, and mimetics.

Is HGH a peptide?
Somatropin is a protein of 191 amino acids. It is often grouped with peptides in research catalogues, but at that length it is classed as a protein hormone.
Is HGH a prescription medicine in Australia?
Somatropin (human growth hormone) is listed in Schedule 4 of the Poisons Standard (prescription only). It is also listed in Appendix D clause 5, which makes possession without authority an offence. Peptides Collective sells it for laboratory research use only.
Is HGH banned in sport?
WADA's 2026 Prohibited List prohibits HGH at all times, under class S2 Peptide hormones, growth factors, related substances, and mimetics.
What is the CAS number for HGH?
The CAS number for HGH is 12629-01-5. Its PubChem CID is None.
How long does an unopened HGH vial keep?
A sealed vial of lyophilised powder keeps to the date on its label when stored frozen, dry and dark. Once reconstituted, keep the solution at 2 to 8 degrees Celsius and record the date on the label.
Does every HGH batch have a certificate?
Yes. Every HGH batch is tested by [lab] before it goes on sale, and the certificate is published under the batch number printed on the vial. The current batch certificate is [pending].
Where is HGH shipped from?
Orders ship tracked from Western Australia. Orders placed before [cut-off] leave the same business day. Delivery estimates by state are on the shipping page.
What purity is the current HGH batch?
The current HGH batch certificate is [pending]. When it is published, it reports purity by HPLC to three decimal places and confirms identity by mass spectrometry.
Which solvent reconstitutes HGH?
BAC Water (sterile water with 0.9% benzyl alcohol) is the usual laboratory solvent. Dilute acetic acid is an alternative for peptides that dissolve poorly in water. Record the solvent, volume and resulting concentration on the vial label.
How much does HGH cost in Australia?
HGH costs A$89 for 15IU at Peptides Collective, in Australian dollars. Each price is per vial of lyophilised powder.
