Ipamorelin vs CJC-1295: Should You Stack or Choose One?
Ipamorelin (GHRP) vs CJC-1295 (GHRH analog): mechanisms, individual effects, and why stacking them together produces synergistically greater GH release than either alone.
Ipamorelin
Ipamorelin acetate
Research OnlyCJC-1295
CJC-1295 DAC
Research OnlyIpamorelin
A selective growth hormone secretagogue and ghrelin mimetic that stimulates GH release without significantly elevating cortisol or prolactin. One of the cleanest and most widely used peptides for body recomposition.
CJC-1295
A synthetic analog of growth hormone-releasing hormone (GHRH) that extends the half-life of endogenous GHRH. One of the most popular peptides for muscle growth and fat loss when stacked with a GHRP like Ipamorelin.

Our Verdict
Winner: Stack both (synergistic)
Ipamorelin (GHRP) and CJC-1295 (GHRH analog) work on two different receptors to produce synergistic GH release. Either alone produces modest GH elevation; combined they produce 3-4x baseline GH pulses. The combination is the gold standard growth hormone peptide protocol and using both is strongly preferred over either alone.
