    Research Compounds

    Tesamorelin

    (Stabilised GHRH 1-44 Analog)

    Selectively reduces visceral abdominal fat, the strongest clinical data of any GHRH analogue, extensively studied for HIV-associated lipodystrophy.

    Hexarelin

    (Examorelin, MF-6003)

    Most potent GHRP analogue with stronger GH pulses than GHRP-2 or GHRP-6, and uniquely cardioprotective.

    Ipamorelin

    (Selective GH-Releasing Pentapeptide)

    Gold standard for low-side-effect growth hormone research, produces a clean GH pulse without raising cortisol, prolactin, or hunger.

    Sermorelin

    (GHRH 1-29 / Growth Hormone-Releasing Factor)

    Restores natural pulsatile growth hormone release without supraphysiological IGF-1 spikes, preferred for anti-aging research and gentler GH-axis support studies.

    CJC-1295 DAC

    (Modified GRF 1-29 with Drug Affinity Complex)

    Sustained week-long GH and IGF-1 elevation, popular for long-acting GH-axis research with minimal injection frequency.

    CJC-1295 (no DAC)

    (Modified GRF 1-29, Mod GRF)

    Tight pulse control for layered GH research stacks, a brief, natural pulsatile GH spike that mirrors physiological release.

    GHRP-2

    (Pralmorelin, KP-102)

    Workhorse of GH-secretagogue research with decades of clinical data, strong GH pulse with moderate appetite stimulation and mild cortisol/prolactin rise.

    GHRP-6

    (Growth Hormone Releasing Hexapeptide)

    Potent ghrelin-mediated GH pulses with strong appetite stimulation, ideal for hard-gainer or bulking research protocols.
