This research peptide blend combines tesamorelin (a stabilized GHRH analog) with ipamorelin (a selective GHS-R1a / ghrelin receptor agonist). In research models, the two molecules activate parallel pathways of the growth hormone axis. Supplied strictly for Research Use Only.
Both blends pair a GHRH analog with ipamorelin, but they use different GHRH backbones. Tesamorelin is an N-terminally modified GHRH(1-44) analog. CJC-1295 is a GHRH(1-29) analog. The two have distinct half-life and receptor-binding profiles in published research.
Tesamorelin stimulates pituitary GH release via the GHRH receptor while ipamorelin stimulates the same cells via the GHS-R1a (ghrelin) receptor. The combined GHRH+GHRP mechanism produces a synergistic GH pulse in research models that neither molecule produces alone.
