About IGF-2
Binds IGF-1R and insulin receptor variant A; promotes anabolic signaling in muscle and fat; activates PI3K/Akt/mTOR pathway; different receptor binding profile than IGF-1
About Ipamorelin
Ipamorelin binds to the ghrelin receptor (GHSR-1a) and stimulates dose-dependent GH release with a clean hormonal profile. Unlike GHRP-6 or hexarelin, it does not significantly stimulate appetite-related pathways or cortisol secretion at standard research doses. This selectivity makes it a frequently studied peptide for protocols where hormonal side-effect profiles are a consideration.

Research protocols routinely measure IGF-1 to track GH axis activity before and during use. Fasting glucose and insulin are monitored because GH elevation can reduce insulin sensitivity over time.

sourceIpamorelin
CJC-1295
Research suggests Ipamorelin and CJC-1295 may produce enhanced growth hormone release effects when combined. CJC-1295 provides sustained GHRH receptor stimulation while Ipamorelin provides pulsatile ghrelin receptor stimulation — complementary pathways studied in GH secretion research.
Sermorelin
Research suggests Sermorelin and Ipamorelin may produce complementary growth hormone release effects when combined. Sermorelin acts as a GHRH analogue via pituitary receptors, while Ipamorelin acts via ghrelin receptors — dual-pathway stimulation studied in GH optimization research.
GLP-1 agonists
Research notes metabolic pathway overlap between growth hormone-releasing peptides and GLP-1 agonists. Both compound classes influence metabolic signaling; limited research has studied their combined effects. Consult your prescriber before combining.
