Sermorelin, CJC 1295 W/O DAC, GHRP-2 and Ipamorelin

Are Sermorelin and CJC 1295 W/O DAC the same class of peptide? Is CJC 1295 W/O DAC thought to be more effective? Dramtically more effective?



Same with GHRP-2 and Ipamorelin. Are they in the same class. Is GHRP-2 thought to be more effective? I read that someone was taking both GHRP-2 and Ipamorelin. Why would you do that?



Thanks
