- Both are GHRH analogs targeting the same receptor, but they differ meaningfully in pharmacokinetics. Sermorelin is essentially the unmodified GHRH(1-29) fragment with a half-life of approximately 10 to 20 minutes. CJC-1295 (no DAC) lasts roughly 30 minutes, and the DAC version extends to days. Sermorelin requires more frequent dosing and produces a more transient GH pulse. CJC-1295's modified amino acid backbone confers greater enzymatic resistance and somewhat more sustained receptor activation per injection. Sermorelin does have a longer clinical history — it previously held FDA approval for pediatric GH deficiency — but that approval has been withdrawn.
