GHRP-6 (5mg x 5) and Ipamorelin (5mg x 5)

GHRP-6 and Ipamorelin are synthetic research peptides commonly used together in experimental models to investigate growth hormone axis regulation and pituitary receptor signaling. GHRP-6 is a hexapeptide growth hormone secretagogue that activates the growth hormone secretagogue receptor (GHS-R1a), engaging Gq/PLC-dependent calcium signaling pathways involved in GH release and hypothalamic–pituitary feedback mechanisms. Ipamorelin is a selective pentapeptide GHS-R1a agonist that promotes GH secretion through calcium-mediated signaling while exhibiting minimal interaction with other pituitary hormone systems in preclinical research. The combined use of GHRP-6 and Ipamorelin enables investigation of complementary GHS-R1a signaling dynamics, receptor pharmacology, and somatotropic pathway modulation.
