What is CJC-1295?
CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH). It is available in two forms: CJC-1295 without DAC (also called Mod GRF 1-29) and CJC-1295 with DAC (Drug Affinity Complex). The DAC version has a significantly extended half-life due to its ability to bind to albumin in the bloodstream.
Research Dosing Parameters
- CJC-1295 no-DAC: 100–200 mcg per injection, 2–3x daily
- CJC-1295 with DAC: 1–2 mg per week
- Common vial size: 2 mg
- Reconstitution: 1–2 mL bacteriostatic water
- Often combined with: Ipamorelin or other GHRPs
How to Reconstitute CJC-1295
- Use bacteriostatic water — inject slowly into the vial
- Do not shake; gently swirl until dissolved
- The solution should be clear
- Store at 2–8°C once reconstituted
- Use no-DAC within 30 days; DAC form may be stable slightly longer
FAQ
What is the difference between CJC-1295 with and without DAC? The DAC version binds to albumin, extending half-life to approximately 8 days. The no-DAC version (Mod GRF 1-29) has a short half-life of ~30 minutes and is typically used 2–3x daily.
Should I use CJC-1295 alone or with ipamorelin? Research commonly combines CJC-1295 (no-DAC) with ipamorelin to create a synergistic GH pulse. Use the multi-peptide feature in the calculator above.
How do I calculate CJC-1295 with DAC dosing? Switch the dose unit to “mg” in the calculator and enter your weekly dose to calculate units for your concentration.
