CJC-1295 vs GHRP-2: Head-to-Head Comparison

CJC-1295 and GHRP-2 represent the two main arms of GH secretion: GHRH and ghrelin pathways. CJC-1295 is a GHRH analog that provides sustained GH elevation, while GHRP-2 is a ghrelin mimetic that triggers acute GH pulses. They are frequently stacked for synergistic effects.
