CJC-1295 / Ipamorelin Blend

The CJC-1295 / Ipamorelin combination is one of the most widely used peptide stacks in the research community. By pairing a GHRH analogue (CJC-1295) with a GHRP (Ipamorelin), the blend produces a synergistic and sustained elevation of growth hormone that neither compound achieves alone.

Quick facts

Half-life
CJC-1295 DAC: ~6–8 days; Ipamorelin: ~2 hours
Administration
Subcutaneous injection
Primary use
Growth hormone optimisation, body composition, recovery

How it works

CJC-1295 increases the amplitude of GH pulses by stimulating GHRH receptors, while Ipamorelin increases the frequency of GH pulses via the ghrelin receptor. Together they produce a more complete and physiologically natural GH release pattern, with Ipamorelin's selectivity keeping cortisol and prolactin low.

Reported benefits

  • Synergistic GH release — greater than either peptide alone
  • Improved lean muscle mass and fat loss over time
  • Enhanced recovery, sleep quality, and tissue repair
  • Clean side effect profile — Ipamorelin limits cortisol and prolactin elevation

Typical dosing protocol

Dosing

CJC-1295 DAC 1–2 mg/week + Ipamorelin 100–300 mcg 2–3x daily; or pre-mixed blends at equivalent ratios

Cycle length

8–12 weeks, followed by a break of 4+ weeks
