Ipamorelin 5mg

Ipamorelin is a synthetic pentapeptide that acts as a ghrelin-receptor (GHS-R1a) agonist. It is selective in receptor assays, which makes it a common reference compound in growth hormone secretagogue research. It is supplied as a lyophilised powder in a 5mg vial.

Research context

Ipamorelin is studied as a selective growth hormone secretagogue: in receptor and animal studies it triggers growth hormone release with little effect on other pituitary hormones such as ACTH and cortisol. It is often researched alongside GHRH analogues such as CJC-1295 (no DAC), which act on a different receptor.

FAQs

What purity is this batch?
The current batch of Ipamorelin tested at 99.41% by HPLC, with identity confirmed by mass spectrometry. The full certificate of analysis, number 026-I81-TSX, is shown below and can be downloaded.

Which receptor does Ipamorelin act on?
The growth hormone secretagogue receptor (GHS-R1a), also known as the ghrelin receptor.

How should it be stored?
Keep the sealed vial at 2–8°C for short-term storage or at −20°C for long-term storage, away from light and moisture. Let a cold vial reach room temperature before opening it.

Is this the same as Ipamorelin acetate?
Yes. Ipamorelin is also written or searched for as Ipamorelin acetate, Ipamoreline or Ipam. All of these names refer to this pentapeptide.

Can I buy Ipamorelin in the UK?
Yes. Absolute Peptides supplies Ipamorelin 5mg from UK stock for laboratory research, with tracked Royal Mail delivery and the batch certificate of analysis on this page. Buyers confirm research use at checkout.

Is Ipamorelin for sale with a certificate of analysis?
Yes. Every vial is from a batch with its own certificate showing HPLC purity and mass spectrometry identity, shown on this page.
