Short answer
What is Ipamorelin?
Ipamorelin is a synthetic 5-amino-acid peptide that acts as a growth hormone secretagogue at the ghrelin receptor.
It also appears in the literature as NNC 26-0161, Aib-His-D-2-Nal-D-Phe-Lys-NH2.
What is in each Ipamorelin vial?
| STRENGTH | FORM | PRICE | CERTIFICATE |
|---|---|---|---|
| 10mg | Lyophilised powder | A$68 | Pending |
What has research on Ipamorelin examined?
Ipamorelin was characterised in cell and animal studies (e.g. rat pituitary cells, swine, rats) in the late 1990s. Human work includes a pharmacokinetic-pharmacodynamic study in healthy volunteers and a randomized phase II proof-of-concept trial in postoperative ileus.
The table lists primary sources by year and model. Findings describe the study subjects, not this research vial.
What adverse events have studies of Ipamorelin reported?
In a phase 2 placebo-controlled trial in 114 bowel-resection patients given intravenous ipamorelin for up to 7 days, treatment-emergent adverse events occurred in 87.5% on ipamorelin and 94.8% on placebo (PMID 25331030). No other human study reporting adverse events was found.
These findings describe the people or animals in each study. The sources list gives every PubMed record.
How do you reconstitute and store Ipamorelin?
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 Ipamorelin the same as MK-677?
No. Ipamorelin is a 5-amino-acid peptide. MK-677 (ibutamoren) is a small non-peptide molecule with the formula C27H36N4O5S. The literature describes both as growth hormone secretagogues.
Is ipamorelin a peptide?
Yes. Ipamorelin is a peptide of 5 amino acids.
Is ipamorelin a prescription medicine in Australia?
Ipamorelin 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 ipamorelin banned in sport?
WADA's 2026 Prohibited List prohibits Ipamorelin at all times, under class S2.2.4.
What is the CAS number for ipamorelin?
The CAS number for Ipamorelin is 170851-70-4. Its PubChem CID is 9831659.
How long does an unopened ipamorelin 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 ipamorelin batch have a certificate?
Yes. Every Ipamorelin 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 ipamorelin 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 ipamorelin batch?
The current Ipamorelin batch certificate is [pending]. When it is published, it reports purity by HPLC to three decimal places and confirms identity by mass spectrometry.
