CJC-1295 (no DAC) vs Sermorelin
CJC-1295 (no DAC) vs Sermorelin: modified vs unmodified GHRH analogs. Half-life, dosing frequency, real-world use.
The verdict
Both are GHRH analogs that restore natural GH pulses; the difference is in the molecule's stability. CJC-1295 (no DAC) is modified to be a bit more robust while still staying short-acting on purpose, and in practice it's almost always paired with Ipamorelin. Sermorelin is the unmodified original, slightly gentler and shorter-lived. For most modern protocols, CJC-1295 + Ipamorelin is the go-to combo. Sermorelin is the simpler, more old-school single option if you want minimal stacking.
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.
Sermorelin is the older, gentler cousin in the GH-axis family. Approved decades ago. Often used by anti-aging clinics for adults with declining GH output. Daily injection at bedtime.
Which one should you pick?
Pick CJC-1295 (no DAC) if users stacking with ipamorelin (the canonical pair) or people wanting gh benefits while preserving the natural pulse rhythm.
Pick Sermorelin if beginners to gh-axis peptides or older adults with declining gh output.

Common questions
- Can you stack CJC-1295 (no DAC) with Sermorelin?
- Neither entry lists the other as a stack partner. Each full entry has its own stacking notes.
- What's the dose difference between CJC-1295 (no DAC) and Sermorelin?
- CJC-1295 (no DAC): 100 mcg sub-q, 1-3x daily, paired 1:1 with Ipamorelin.
- Sermorelin: 200-500 mcg sub-q nightly, on an empty stomach. Some protocols use 100-300 mcg twice daily.
- Is CJC-1295 (no DAC) or Sermorelin FDA approved?
- CJC-1295 (no DAC): Not FDA approved.
- Sermorelin: Approved as Geref (1997) for treatment of pediatric growth hormone deficiency. Discontinued by the manufacturer around 2008 for commercial reasons (the FDA's 2013 determination explicitly states it was not withdrawn for safety or effectiveness). Now compounded-only, not FDA-approved as a finished product.
- What are the side effects of CJC-1295 (no DAC) vs Sermorelin?
- CJC-1295 (no DAC): Head-rush; Brief facial flush; Hunger pulse.
- Sermorelin: Head-rush at injection; Hunger pulse 30-60 min post-dose; Mild flushing.
