Growth Hormone Secretagogues17

IpamorelinB
VS
CJC-1295B

Ipamorelin is a selective ghrelin mimetic (GHRP) that triggers GH pulses, while CJC-1295 is a GHRH analog that amplifies GH release duration. They are commonly combined because the...

IpamorelinB
VS
GHRP-2B

Both are ghrelin mimetics that stimulate GH release, but GHRP-2 is more potent at the cost of greater side effects. Ipamorelin is considered the cleanest GHRP with virtually no imp...

IpamorelinB
VS
HexarelinB

Hexarelin is the most potent GHRP available, producing the strongest GH release of any ghrelin mimetic, but at the cost of significant cortisol and prolactin elevation. Ipamorelin ...
