Secretagogue
Ipamorelin
Selective GH Secretagogue
Ipamorelin is a selective growth-hormone secretagogue that acts as a ghrelin-receptor (GHS-R1a) agonist. It is valued in research for its selectivity: it stimulates GH-secretagogue signaling with minimal effect on cortisol or prolactin in preclinical models, distinguishing it from earlier, less-selective GHRPs.
In vitro and preclinical studies examine ghrelin-receptor binding dynamics, pulsatile GH-release signaling, and downstream neuroendocrine pathways, and it is frequently modeled alongside GHRH analogues such as CJC No-DAC and tesamorelin to study complementary secretagogue mechanisms. Supplied as a lyophilized 10-vial kit in 5mg and 10mg sizes for in vitro research use only.

Common Questions
Ipamorelin FAQ
What is Ipamorelin?+
Ipamorelin is a Selective GH Secretagogue supplied for laboratory research. Selective ghrelin mimetic investigated in vitro for GH secretagogue receptor binding dynamics, pulse stimulation pathway modeling, and neuroendocrine signaling research.
Why is Ipamorelin often studied together with CJC-1295?+
Ipamorelin is a selective GH secretagogue (a ghrelin mimetic), while CJC-1295 is a GHRH analogue. Because they stimulate growth-hormone release through complementary pathways, they are frequently paired in research.
What is lyophilized Ipamorelin, and how is it reconstituted?+
Ipamorelin is supplied as a lyophilized (freeze-dried) powder, a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently, never shaken, until the powder fully dissolves. All handling is for in vitro research use only.
How should Ipamorelin be stored?+
Store the lyophilized Ipamorelin powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.
What is the purity of Ipamorelin, and how is it tested?+
Every batch of Ipamorelin is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods: high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
