Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue receptor (GHSR-1a) agonist. Used in controlled research environments to map receptor binding kinetics, profile downstream second-messenger responses, and compare selectivity against other GH-axis secretagogues in non-clinical in-vitro models.

Ipamorelin is a synthetic pentapeptide GH secretagogue that selectively engages the growth hormone secretagogue receptor (GHSR-1a) without significantly stimulating cortisol or prolactin secretion pathways — a selectivity profile that makes it particularly useful for isolating GH-axis-specific receptor pharmacology in research models.

Researchers employ Ipamorelin to map GHSR-1a binding characteristics, profile downstream second-messenger responses (including cAMP and intracellular calcium mobilisation), and compare potency and selectivity against other secretagogues such as GHRP-6 and GHRP-2 in cell-based assays. Work focuses on receptor pharmacology and pathway profiling exclusively in controlled, non-clinical environments.

Ipamorelin is commonly studied in combination with GHRH analogues such as CJC-1295 (no DAC) to characterise synergistic receptor engagement along the GH-axis. Supplied as a lyophilised powder, stable and straightforward to store and reconstitute.

01
Allow to reach room temperature

Remove the vial from cold storage and allow it to reach room temperature before opening. This prevents condensation forming inside the vial and disturbing the lyophilised powder.

02
Use bacteriostatic water

Always reconstitute with bacteriostatic water (BW). Avoid distilled or sterile water for long-term storage — BW contains 0.9% benzyl alcohol which preserves peptide stability and prevents microbial growth.

03
Inject slowly along the inside wall

Insert the needle into the vial and allow BW to run slowly down the inside wall. Do not inject directly onto the lyophilised powder — the pressure can degrade the peptide structure.

04
Gently swirl until dissolved

Gently swirl the vial — never shake. Continue until the powder is fully dissolved and the solution is clear. Shaking introduces air bubbles and can cause aggregation.

05
Store reconstituted vials at 2–8°C

Once reconstituted, store at 2–8°C and use within 30 days. Never freeze a reconstituted vial. Lyophilised (un-reconstituted) vials should be stored at –20°C, away from direct light.

Very satisfied with the product. Would benefit from a fuller COA showing mass spec data alongside HPLC, but the purity level itself is not in question.
