CJC + Ipamorelin Same as CJC-1295 No DAC & Ipamorelin: Comparison
Peptide Structure Modified GRF 1–29 (29 amino acids, 4 substitutions) + Ipamorelin pentapeptide Identical. Modified GRF 1–29 + Ipamorelin CJC-1295 with maleimidoproprionic acid linker + Ipamorelin Same peptides, different shorthand Half-Life ~30 minutes (CJC n
This comparison does not assign a generated winner or score.
- Peptide Structure
- Modified GRF 1–29 (29 amino acids, 4 substitutions) + Ipamorelin pentapeptide
- Identical. Modified GRF 1–29 + Ipamorelin
- CJC-1295 with maleimidoproprionic acid linker + Ipamorelin
- Same peptides, different shorthand
- Half-Life
- ~30 minutes (CJC no DAC) + ~2 hours (Ipamorelin)
- ~30 minutes + ~2 hours
- ~6–8 days (CJC with DAC) + ~2 hours (Ipamorelin)
- No-DAC version matches Ipamorelin kinetics
- Dosing Frequency
- Daily or twice-daily pulsatile dosing
- Weekly CJC + daily Ipamorelin (pharmacokinetic mismatch)
- Pulsatile protocols require no-DAC
- Synergistic Effect
- Full synergy. Both peptides clear within hours, pulse effect intact
- Full synergy. Matched kinetics
- Partial synergy. Only first 2–3 hours post-dose aligned
- Matched half-lives maximize GH amplitude
- Typical Research Dose Range
- 100–200 mcg CJC + 200–300 mcg Ipamorelin per dose
- 1–2 mg CJC weekly + 200–300 mcg Ipamorelin daily
- Dose ranges identical for no-DAC blends
