Ipamorelin
Ipamorelin is a lab-made peptide of just five amino acids, developed at Novo Nordisk in the 1990s.
Where it came from
Ipamorelin was developed at the Danish company Novo Nordisk and described in 1998 by Kirsten Raun and colleagues in the European Journal of Endocrinology. It was derived from an earlier peptide, GHRP-1.
Worth knowing
- It is a chain of just five amino acids, weighing about 712 units.
- Three of its five building blocks are lab-made versions not found in natural proteins, two of them mirror-image forms of common amino acids.
- Its Novo Nordisk code name was NNC 26-0161. The "-relin" ending is the official naming pattern for lab-made versions of releasing hormones.

Weight is shown in grams per mole (g/mol), the standard unit chemists use. It's the number a lab checks a sample against to confirm it's the right compound.
Lab reports
Every batch (called a lot) of Ipamorelin is tested by an independent lab. The report shows the lab, the test date, the lot number, how pure the sample is and how much is in the vial. Find them on the Certificates of Analysis page. New to lab reports? Start with How to read a peptide lab report.
The weight above is for the compound on its own. A report may show a slightly higher figure, because the powder also carries a little salt left from manufacturing. Peptide salt forms explains why.
Storage
Keep the vial sealed in a freezer at -20 °C, away from light, and let it warm to room temperature before opening so moisture doesn't get in. More in Storing lyophilized (freeze-dried) peptides in the lab and the Research handling guidelines.
