    Description

    MB1® Ipamorelin is a high-purity peptide available in a 5mg lyophilized powder format, intended strictly for laboratory research and development use. Engineered to meet or exceed 99% purity and verified through both HPLC and LC-MS testing protocols, this research-grade peptide is provided in a sterile, sealed vial to preserve stability, potency, and integrity throughout its shelf life.

    Selective GH Secretagogue

    The Most Selective Growth Hormone Secretagogue Known

    Ipamorelin is a pentapeptide ghrelin receptor agonist that selectively stimulates pulsatile growth hormone release without affecting other pituitary hormones. Unlike older GHRPs, ipamorelin has no measurable effect on ACTH, cortisol, prolactin, FSH, LH, or TSH — making it the "cleanest" GH secretagogue available for research. This exceptional selectivity has made it both a therapeutic candidate and a model compound for understanding receptor specificity.

    • Pentapeptide sequence: Aib-His-D-2Nal-D-Phe-Lys-NH₂
    • Binds GHSR-1a (ghrelin receptor) with high selectivity
    • No effect on ACTH, cortisol, prolactin, FSH, LH, or TSH
    • Pulsatile GH release (peak ~40 min, t½ ~2 hours)
    • Respects physiologic GH rhythms
    Precision GH Signaling

    How Ipamorelin Achieves Unmatched Selectivity

    Ipamorelin functions as a "precision tap" on the GH axis. By activating GHSR-1a without triggering broader pituitary responses, it produces a brief, physiologic-like GH pulse that returns to baseline — unlike GHRP-6 or hexarelin which act more like "broad faucets" causing neuroendocrine spillover. In animal studies, ipamorelin showed no ACTH/cortisol elevation even at doses >200× its GH ED50.

    • Activates GHSR-1a on pituitary somatotrophs
    • Synergizes with endogenous GHRH pathway
    • Counteracts somatostatin inhibitory tone
    • No ACTH/cortisol elevation at >200× GH-effective dose
    • Minimal neuroendocrine "noise" vs. older GHRPs
    Research Applications

    From Bone Protection to Metabolic Research

    Ipamorelin research spans multiple therapeutic areas. Studies demonstrate its ability to counteract glucocorticoid-induced bone loss (4× increase in bone formation), improve nitrogen balance, potentiate insulin release, and accelerate GI recovery. Its selectivity also makes it valuable as a diagnostic probe — radiolabeled ipamorelin can image ghrelin receptor expression in cancer and heart failure research.

    • Bone health: Counteracts glucocorticoid-induced bone loss
    • Muscle preservation: Improves nitrogen balance
    • Metabolic research: Potentiates insulin release
    • GI function: Accelerates post-operative recovery
    • Diagnostic imaging: PET probe for GHSR-1a expression
