Aib-His-D-2-Nal-D-Phe-Lys-NH₂
Physical Properties
Ipamorelin is a synthetic pentapeptide containing non-natural amino acid residues such as Aib (α-aminoisobutyric acid) and D-configured aromatic residues, which enhance resistance to enzymatic degradation compared to peptides composed solely of L-amino acids. These structural modifications contribute to improved stability under controlled research conditions. Its short chain length supports efficient aqueous solubility and practical laboratory handling. Lyophilized storage and protection from moisture, light exposure, and repeated freeze–thaw cycles help preserve peptide integrity and maintain analytical consistency during research applications.

Frequently Asked Questions
What is Ipamorelin?
Ipamorelin is a synthetic five–amino acid peptide designed to activate the GHS-R1a receptor in experimental models. It is commonly used in laboratory research focused on growth hormone signaling mechanisms.
What is Ipamorelin commonly researched for?
In controlled laboratory and preclinical models, Ipamorelin is studied for:
-
Growth hormone release signaling
-
Ghrelin receptor (GHS-R1a) activation
-
IGF-1 pathway investigation
-
Endocrine and metabolic pathway research
All applications are exploratory and conducted in research settings.
How does Ipamorelin differ from other GHRPs?
Ipamorelin is structurally distinct from peptides such as GHRP-2, GHRP-6, and Hexarelin. In research models, it is often noted for its receptor selectivity, which may influence downstream signaling characteristics compared to other growth hormone secretagogues.
Is Ipamorelin the same as GHRH analogs like CJC-1295?
No. Ipamorelin primarily activates the ghrelin receptor (GHS-R1a), whereas GHRH analogs such as CJC-1295 act through the GHRH receptor. While both are studied in growth hormone–related research, their mechanisms differ.
How is Ipamorelin supplied?
Ipamorelin is typically supplied as a lyophilized (freeze-dried) powder in sealed research vials to maintain stability during storage and shipment.
How should unreconstituted Ipamorelin be stored?
Lyophilized Ipamorelin should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
How should reconstituted Ipamorelin be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Gently swirl to mix; avoid vigorous agitation
Does Ipamorelin require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch, verifying peptide identity, purity, and analytical testing results to ensure research quality and traceability.
