Short answer
What is Tesamorelin?
Tesamorelin is a synthetic analogue of human growth hormone-releasing factor (GHRH 1-44) with a trans-3-hexenoyl group added at the N-terminus.
It also appears in the literature as TH9507, (3E)-hex-3-enoylsomatoliberin.
What is in each Tesamorelin vial?
| STRENGTH | FORM | PRICE | CERTIFICATE |
|---|---|---|---|
| 10mg | Lyophilised powder | A$128 | Pending |
What has research on Tesamorelin examined?
Tesamorelin has been examined in multiple randomized, placebo-controlled human trials, mainly in HIV-associated abdominal fat accumulation and HIV-associated fatty liver disease, with smaller trials in other groups. PubChem records an FDA-labelled indication in HIV lipodystrophy.
The table lists primary sources by year and model. Findings describe the study subjects, not this research vial.
What adverse events have studies of Tesamorelin reported?
In HIV trials, adverse events did not differ significantly from placebo over 26 weeks, but more tesamorelin recipients withdrew because of an adverse event (PMID 18057338). Injection-site complaints were more frequent than with placebo (PMID 31611038), and fasting glucose rose transiently at 2 weeks (PMID 25038357).
These findings describe the people or animals in each study. The sources list gives every PubMed record.
How do you reconstitute and store Tesamorelin?
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 Tesamorelin legal to buy in Australia?
Tesamorelin is not named individually in the Poisons Standard. The Schedule 4 group entry for growth hormone-releasing hormones (GHRHs), also listed in Appendix D clause 5, appears to cover it; the TGA can confirm. Source: the June 2026 Poisons Standard instrument (F2026L00633).
WADA's 2026 Prohibited List prohibits Tesamorelin at all times, under class S2.2.4.

Tesamorelin questions
What adverse events have studies of tesamorelin reported?
In HIV trials, adverse events did not differ significantly from placebo over 26 weeks, but more tesamorelin recipients withdrew because of an adverse event (PMID 18057338). Injection-site complaints were more frequent than with placebo (PMID 31611038), and fasting glucose rose transiently at 2 weeks (PMID 25038357).
Is tesamorelin a peptide?
Yes. Tesamorelin is a peptide of 44 amino acids.
Is tesamorelin a prescription medicine in Australia?
Tesamorelin is not named individually in the Poisons Standard. The Schedule 4 group entry for growth hormone-releasing hormones (GHRHs), also listed in Appendix D clause 5, appears to cover it; the TGA can confirm. Peptides Collective sells it for laboratory research use only.
Is tesamorelin banned in sport?
WADA's 2026 Prohibited List prohibits Tesamorelin at all times, under class S2.2.4.
What is the CAS number for tesamorelin?
The CAS number for Tesamorelin is 218949-48-5. Its PubChem CID is 16137828.
How long does an unopened tesamorelin 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 tesamorelin batch have a certificate?
Yes. Every Tesamorelin 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 tesamorelin 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 tesamorelin batch?
The current Tesamorelin 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 tesamorelin?
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 tesamorelin cost in Australia?
Tesamorelin costs A$128 for 10mg at Peptides Collective, in Australian dollars. Each price is per vial of lyophilised powder.
Does tesamorelin ship with a cold pack?
[Cold-pack policy from Nico.] Lyophilised powder tolerates short transit at room temperature. Refrigerate or freeze the vial on arrival.
