CJC-1295 vs Ipamorelin vs Stacked Protocol: Muscle Gain Comparison
CJC-1295 Alone (2 mg/week) +120–180% 140–160 2.1–2.8 kg None measured Extends GH pulse duration but doesn't amplify magnitude. Effective for baseline optimization but limited hypertrophic stimulus Ipamorelin Alone (600–900 mcg/day, divided doses) +80–140% 110–

- CJC-1295 Alone (2 mg/week)
- +120–180%
- 140–160
- 2.1–2.8 kg
- None measured
- Extends GH pulse duration but doesn't amplify magnitude. Effective for baseline optimization but limited hypertrophic stimulus
- Ipamorelin Alone (600–900 mcg/day, divided doses)
- +80–140%
- 110–130
- 1.6–2.3 kg
- None (ghrelin-selective)
- Amplifies pulse magnitude but short half-life requires frequent dosing. Best for pulsatile GH optimization around training windows
- CJC-1295 + Ipamorelin Stack
- +200–400%
- 160–190
- 3.2–4.8 kg
- Synergistic amplification of both pulse duration and magnitude. The most consistent protocol for measurable lean mass accrual in research settings
- Baseline (No Peptide Support)
- 0% (reference)
- 80–100
- 1.1–1.5 kg
- N/A
- Natural training adaptation occurs but recovery limitation constrains training frequency and volume progression
