Read alongside CJC-1295 (no DAC)
Compounds this one is commonly compared with, combined with, or mistaken for. Listing a pairing is not a suggestion to run them together.
- CJC-1295 with DACResearch use onlyOne name, two different compounds. The DAC version has a half-life measured in days; without DAC it is short-acting. Protocols that omit the suffix are ambiguous and should not be followed as written.
- IpamorelinResearch use onlyThe most commonly paired secretagogue combination — a GHRH analogue alongside a GHRP.
- SermorelinPrescription / compoundedBoth GHRH analogues. CJC-1295 without DAC is a modified GRF(1-29); sermorelin is the unmodified sequence, and is the one with an approved-drug history.

IV infusion in 10 normal men: disappearance half-time 4.3 +/- 1.4 min for GHRH(1-29)-NH2 and 6.7 +/- 0.5 min for the D-Ala2 analogue, with MCR falling from 39.7 to 21 mL/kg/min. D-Ala2 is one of the substitutions in modified GRF(1-29), so the backbone clears in SINGLE-DIGIT MINUTES. No primary PK study of the full tetrasubstituted peptide exists, and the widely repeated 30 min figure has no published source and is not consistent with this data. Null rather than a fabricated number.
