About Ipamorelin

Ipamorelin is the most selective growth-hormone-releasing peptide developed. Unlike earlier GHRPs (GHRP-2, GHRP-6), it activates the ghrelin receptor (GHS-R1a) to trigger GH release without the off-target cortisol, prolactin, or aldosterone spike that complicates the interpretation of GHRP data. Why selectivity matters in research: A peptide that elevates cortisol + GH simultaneously is useless for studying GH-specific effects because you can’t isolate the variable. Ipamorelin’s clean profile lets researchers attribute downstream changes to GH release alone. IF the research question is endogenous GH pulsatility with minimal confounders, THEN Ipamorelin is the GHRP with the most defensible selectivity profile. SO it’s the default choice when pairing a GHRP with a GHRH analog (CJC-1295) in GH-axis research. Batch-verified ≥99% purity.
