Ipamorelin vs CJC-1295 (no DAC)

Ipamorelin vs CJC-1295: how they differ mechanistically and why the standard protocol pairs them.

The verdict

Ipamorelin tells the pituitary to fire a GH pulse; CJC-1295 (no DAC) makes each pulse bigger by mimicking GHRH. They work through different receptors, so stacking them produces a cleaner, stronger pulse than either alone, which is why the standard GH-axis protocol pairs them instead of picking one. On its own, Ipamorelin is the gentler, more selective single peptide; CJC-1295 by itself does little of interest. For almost everyone the answer is 'both, together,' usually dosed before bed.

006
Ipamorelin
GH-axisEvidence: Limited

Ipamorelin gently nudges your body to release more of its own growth hormone, without the side effect baggage of injecting actual HGH. People run it for sleep, recovery, and slow body-comp shifts. Tiny doses, multiple times a day.

CJC-1295 (no DAC)
GH-axisEvidence: Limited

CJC-1295 (the 'no-DAC' version) is the partner peptide to Ipamorelin. Together they push a stronger natural GH pulse. Always paired, never run alone in this protocol.

Which one should you pick?

Pick Ipamorelin if users wanting gh benefits without the bloat / sides of hgh or sleep / recovery focused stacks.

Pick CJC-1295 (no DAC) if users stacking with ipamorelin (the canonical pair) or people wanting gh benefits while preserving the natural pulse rhythm.

Note: these two are commonly stacked together rather than chosen between. See the entries for the canonical protocol.
