Head-to-head
CJC-1295 vs Sermorelin
Both stimulate the pituitary to release growth hormone naturally — preserving feedback loops, unlike exogenous HGH. CJC-1295 (no-DAC) is the modern preference; Sermorelin is the older, gentler, budget option.
Side by side
| Feature | CJC-1295 | sermorelin |
|---|---|---|
| Class | GHRH analog (modified, no-DAC) | GHRH analog (1-29 fragment) |
| Half-life (no-DAC version) | ~30 minutes | ~10–20 minutes |
| GH pulse amplitude | Higher amplitude | Lower, more physiological |
| Dose | 1 mg before bed (or '10 unit mark') | 300 mcg men / 200 mcg women nightly |
| Always paired with | Ipamorelin (1+1=3 effect) | Optional Ipamorelin pairing |
| Cycle | 5 days on / 2 off, 8–12 week cycles | 3–6 month cycles, 1 month off |
| Cost | $150–200/mo with Ipa | $80–120/mo (cheaper) |
| Best for | Performance, muscle, sleep depth | Sleep, gentle anti-aging, beginners |
| DAC version warning | Avoid DAC version (Dr. Jones DC) — 6–8 day no-off-switch | N/A |
Who wins, by goal
Performance / muscle building
Higher GH pulse amplitude. Hunter Williams: 'Sermorelin is obsolete' for performance use.
Budget-conscious / beginner
JD Denham, Froese: gentler, cheaper, perfectly fine for sleep and recovery.
Sleep depth (primary goal)
Both improve deep sleep similarly. CJC has more data; Sermorelin is sufficient.
Older adults (50+)
Pituitary aging means less endogenous GH stimulation — CJC's higher amplitude pulse compensates.
Gentler approach / minimum effective dose
More physiological pulse pattern. Less amplitude = less feedback disruption.
Where the experts land
Hunter Williams calls Sermorelin 'obsolete' vs CJC no-DAC. JD Denham, XSculpt, Froese still use Sermorelin for budget/beginner cases. Bachmeyer, Jones DC, Trigili, Jay Campbell all endorse CJC + Ipamorelin as the modern foundation.
Bottom line
If you're serious and budget allows: CJC-1295 (no-DAC) + Ipamorelin. If you're budget-limited or just want better sleep without performance goals: Sermorelin is sufficient. Whichever you choose, dose at night.
