CJC/Ipamorelin Blend Calculator
The CJC/Ipa blend is a community term for a combined vial containing CJC-1295 (no DAC) and Ipamorelin — the same two peptides discussed in the GH stack. A common formulation is 2 mg of each for a 4 mg total vial, reconstituted with 2 mL of bacteriostatic water. Editable below.

Components in the CJC/Ipamorelin Blend
Each peptide in this blend has its own individual calculator page with factual information on vial sizes, reported half-life, and storage. Compositions vary by vendor — the mg ratios above are defaults based on commonly cited formulations.
- CJC-1295 (no DAC) — A modified GHRH analog that binds to pituitary GHRH receptors to stimulate pulsatile growth hormone release.
- Ipamorelin — A selective pentapeptide growth hormone releasing peptide that activates the ghrelin receptor to stimulate pituitary GH release.

How to use this calculator
The CJC/Ipamorelin Blend calculator handles two dose-targeting modes:
- Target total blend dose — "I want 2 mg of the blend per injection." The calculator returns the draw volume and reports how much of each component you're getting at that draw.
- Target specific component — "I want 250 mcg of BPC-157 specifically." The calculator back-calculates the draw from that component's concentration, and reports incidental amounts of the other components delivered at the same draw.
If your vial's stated total mg differs from the sum of component mg values (common on vendor labels — rounding, copper-ion mass, excipients), the calculator flags the mismatch and uses the component sum as the authoritative total for math purposes.
