CJC-1295 + Ipamorelin Stack

Understanding why this combo works requires knowing how GH is naturally released. Your pituitary gland releases GH in pulses triggered by two signals: GHRH (growth hormone releasing hormone) tells the pituitary to release, and GHRP (growth hormone releasing peptide) amplifies the pulse intensity.

CJC-1295 is a GHRH analog—it primes the pituitary. Ipamorelin is a GHRP—it triggers the release. Together, they produce a synergistic GH pulse 3–5x larger than either compound alone. This pulsatile pattern is more effective and safer than the flat-line elevation from exogenous HGH.

Two forms of CJC-1295 exist—choose carefully:

• CJC-1295 without DAC (Mod GRF 1-29) — Preferred for stacking. Short half-life (~30 minutes) that produces clean, natural GH pulses when paired with ipamorelin.
• CJC-1295 with DAC — Longer half-life (~8 days) due to Drug Affinity Complex. Creates more sustained but less pulsatile GH elevation. Less commonly used in stacks.
• Ipamorelin — The cleanest GHRP available. Unlike GHRP-6 or GHRP-2, ipamorelin does not significantly raise cortisol, prolactin, or cause intense hunger spikes.

For optimal pulsatile GH release, CJC-1295 without DAC + ipamorelin is the standard protocol.

Both peptides should be administered on an empty stomach—no food for at least 1 hour before and 30 minutes after injection. Fats and carbohydrates blunt GH release significantly. The pre-bed dose is considered the most important as it amplifies the natural nocturnal GH surge.

Weeks 1–2: Improved sleep quality is typically the first benefit noticed. Deeper, more restorative sleep with vivid dreams. Subtle increases in energy throughout the day.

Weeks 3–6: Body composition changes begin. Fat loss (especially abdominal), improved skin quality, and increased recovery from exercise. Strength may begin increasing.

Weeks 6–16: Full effects. Significant lean mass gains, reduced body fat percentage, improved hair and skin, enhanced mood, and stronger immune function. IGF-1 levels peak after 8–12 weeks of consistent use.

The CJC-1295/ipamorelin stack is one of the best-tolerated peptide combinations. Side effects may include mild water retention, tingling or numbness in extremities (carpal tunnel-like symptoms from GH), and increased appetite. These effects are dose-dependent and typically mild.

Precautions: Monitor fasting glucose—GH elevation can reduce insulin sensitivity over time. Cycle 12–16 weeks on, 4–8 weeks off. Avoid if you have active cancer or diabetes. Blood work every 8–12 weeks is recommended (IGF-1, fasting glucose, insulin).

CJC-1295 and ipamorelin are peptides where purity directly determines efficacy. Low-quality versions may contain degraded fragments that simply don't work. Ascension Peptides provides:

• 99%+ purity CJC-1295 and ipamorelin verified by HPLC
• Properly lyophilized with accurate dosing per vial
• Batch-specific certificates of analysis
