Gold Standard GH Stack

CJC-1295 + Ipamorelin Stack Guide

The gold standard growth hormone peptide stack. Optimal dosing, timing, and protocol for maximizing natural GH release.

Updated April 2026·6 min read

Why This Stack Works

CJC-1295 (no DAC / Mod GRF 1-29) is a GHRH analog that tells your pituitary to produce growth hormone. Ipamorelin is a GHRP that tells your pituitary to release it. Together, they produce a GH pulse that is 3-5x larger than either peptide alone. This synergistic effect is why the combination is considered the gold standard for peptide-based growth hormone optimization.

The key advantage of ipamorelin over other GHRPs (like GHRP-6 or GHRP-2) is its selectivity. Ipamorelin does not significantly raise cortisol or prolactin and causes minimal hunger increase, making it the cleanest option for daily use.

Recommended Stack Protocol

CJC-1295 no DAC (Mod GRF 1-29)

100 mcg per injection — 2-3x daily

Must be injected on an empty stomach (2+ hours fasted). Wait 20-30 min before eating after injection.

Ipamorelin

100-200 mcg per injection — 2-3x daily

Same timing as CJC-1295. Both are drawn into the same syringe and injected together.

Optimal Daily Schedule

Morning (fasted)
100mcg CJC + 100mcg Ipam
Before breakfast
Post-workout
100mcg CJC + 100mcg Ipam
Before post-WO meal
Before bed (fasted 2+hrs)
100mcg CJC + 200mcg Ipam
Most important dose

Why the Pre-Bed Dose Matters Most

Your body produces its largest natural GH pulse approximately 1 hour after falling asleep. Injecting CJC-1295 + ipamorelin 30 minutes before bed on an empty stomach amplifies this natural pulse dramatically. If you can only dose once daily, make it the pre-bed dose.

Cycling

Most protocols recommend 8-12 weeks on, followed by 4 weeks off to prevent receptor desensitization. Some users run 5 days on / 2 days off (weekdays only) as an alternative cycling approach.
