    • Growth-Hormone Research Peptides

    Growth-hormone secretagogue research compounds from both receptor classes studied in pituitary release models: GHRH analogues that act at the GHRH receptor, and ghrelin-receptor (GHS-R1a) agonists that act at a separate site. Half-life is the main practical difference within each class, from minutes to several days. Supplied for laboratory research only.

    • Ipamorelin

    ★★★★★ ★★★★★ 4.5 4 reviews

    (Selective GH-Releasing Pentapeptide)

    Ipamorelin is a five-amino-acid growth-hormone secretagogue that acts at the ghrelin receptor GHS-R1a. Investigated for pituitary GH-release signalling and receptor selectivity in endocrine research.

    Tesamorelin

    ★★★★★ ★★★★★ 4.3 14 reviews

    (Stabilised GHRH 1-44 Analog)

    Tesamorelin is a stabilised growth-hormone-releasing hormone analogue based on GHRH(1-44). Relevant research examines GHRH-receptor activation, pituitary growth-hormone release and GH/IGF-1 endocrine signalling.

    CJC-1295 (no DAC)

    (Modified GRF 1-29, Mod GRF)

    CJC-1295 without DAC is a modified GRF(1-29) analogue lacking the albumin-binding drug affinity complex. Studied for GHRH-receptor activity and short-duration growth-hormone-axis signalling.

    CJC-1295 (with DAC)

    (Modified GRF 1-29 with Drug Affinity Complex)

    CJC-1295 with DAC is a modified GHRH analogue containing an albumin-binding drug affinity complex. Research compares prolonged GHRH-receptor signalling with shorter-acting GRF analogues.

    Sermorelin

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

    Sermorelin is the N-terminal 29-amino-acid fragment of growth-hormone-releasing hormone. Used in endocrine research examining GHRH-receptor activation and pulsatile pituitary GH signalling.

    Hexarelin

    ★★★★★ ★★★★★ 5 1 review

    (Examorelin, MF-6003)

    Hexarelin is a synthetic growth-hormone-releasing hexapeptide and ghrelin-receptor agonist. Investigated in endocrine studies of GH release and receptor interactions, including GHS-R1a and CD36.

    GHRP-2

    (Pralmorelin, KP-102)

    GHRP-2 (pralmorelin) is a synthetic hexapeptide agonist of the ghrelin receptor. Studied in endocrine research for growth-hormone secretagogue activity and related hypothalamic-pituitary pathways.

    GHRP-6

    (Growth Hormone Releasing Hexapeptide)

    GHRP-6 is a synthetic growth-hormone-releasing hexapeptide that activates the ghrelin receptor. Investigated in GH-secretion and ghrelin-receptor signalling models.

    What you will find here

    Sermorelin is GHRH(1-29). CJC-1295 without DAC (Mod GRF 1-29) carries four amino-acid substitutions, including D-Ala2 for DPP-IV resistance. CJC-1295 with DAC carries a Drug Affinity Complex that binds albumin, extending its half-life to roughly a week. Tesamorelin is a GHRH(1-44) analogue with an N-terminal hexenoic-acid group. On the ghrelin-receptor side, ipamorelin is studied as a selective GHS-R1a agonist. GHRP-2 and GHRP-6 are hexapeptide GHS-R1a agonists. Hexarelin, a related hexapeptide, also binds the CD36 receptor. Because the two classes act at different receptors, published models often pair one GHRH analogue with one ghrelin-receptor agonist, and each product page states the strengths available.
