    What Is Ipamorelin?

    Ipamorelin is a synthetic pentapeptide (5 amino acids) that functions as a selective growth hormone releasing peptide (GHRP). It acts as a ghrelin receptor agonist, stimulating the pituitary to release growth hormone in pulsatile patterns.

    In laboratory research, Ipamorelin is studied for:

    • Selective GH secretagogue activity
    • Ghrelin receptor pathway characterization
    • Pulsatile hormone release patterns
    • Minimal effect on cortisol and prolactin in models

    Its selectivity profile makes Ipamorelin particularly valuable for isolated pathway studies without confounding variables from other hormone systems.

    What Is CJC-1295?

    CJC-1295 is a synthetic analog of growth hormone releasing hormone (GHRH), consisting of 29 amino acids with modifications to extend its biological activity. The DAC (Drug Affinity Complex) version provides significantly extended duration of action.

    In research settings, CJC-1295 is studied for:

    • GHRH receptor pathway activation
    • Sustained growth hormone elevation models
    • IGF-1 axis research
    • Extended-release peptide pharmacokinetics

    The extended half-life of CJC-1295 makes it useful for studying prolonged receptor activation and downstream signaling effects.

    Key Differences for Researchers

    These compounds represent two distinct approaches to growth hormone pathway research:

    Receptor Pathways

    Ipamorelin activates the ghrelin (GHS-R1a) receptor, while CJC-1295 targets the GHRH receptor. These distinct pathways offer different research models for understanding GH regulation.

    Release Patterns

    Ipamorelin research typically shows pulsatile GH release patterns similar to physiological rhythms. CJC-1295 studies often demonstrate more sustained elevation due to its extended half-life.

    Selectivity Profile

    Ipamorelin is noted in research for its selectivity, with minimal effects on cortisol and prolactin pathways. CJC-1295 as a GHRH analog has a different selectivity profile relevant to its receptor target.

    Combination Research

    Many research protocols examine both compounds together to study potential synergistic effects when activating both receptor pathways simultaneously, which is why we offer a CJC-1295 + Ipamorelin blend.

    Frequently Asked Questions

    What is the difference between GHRP and GHRH peptides?

    GHRPs like Ipamorelin work through the ghrelin receptor pathway to stimulate growth hormone release in pulses. GHRHs like CJC-1295 work through the GHRH receptor to amplify and sustain growth hormone secretion. They operate through distinct but complementary mechanisms.

    Why are these peptides often studied together?

    Researchers frequently examine both compounds because they target different receptor pathways that converge on growth hormone release. Studying them together helps understand potential synergistic effects and pathway interactions.

    Are these compounds approved for human use?

    No. These are research compounds intended strictly for laboratory investigation. They are not approved for human or veterinary use. All Maple Research Labs products are sold for research purposes only.

    What documentation is available?

    All products have batch-specific Certificates of Analysis available with HPLC purity verification, mass spectrometry identity confirmation, and synthesis documentation.

    How should these peptides be stored?

    Lyophilized peptides should be stored at -20°C in a dry environment protected from light. Reconstituted peptides require refrigeration at 2-8°C and should be used within recommended timeframes.
