CJC-1295 Calculator
CJC-1295 (also known as Modified GRF 1-29 (DAC)) reconstitution and dosage reference — calculate vial concentration, BAC water volume, and exact syringe units below.
Also known as: Modified GRF 1-29 (DAC), Mod-GRF 1-29
At the reference preset of a 5mg CJC-1295 vial reconstituted with 2 mL of bacteriostatic water, a 0.1mg dose measures 4 units on a U-100 insulin syringe.
CJC-1295 is a synthetic analogue of growth-hormone-releasing hormone (GHRH).

How to use this calculator›
- 1. Vial — the peptide amount printed on the vial, in milligrams.
- 2. BAC water — the bacteriostatic water added to the vial. More water means a lower concentration and a larger, easier-to-read draw.
- 3. Dose — the single dose being measured, in milligrams.
- 4. Syringe — the barrel being drawn into. The diagram rescales to that syringe, so the same dose sits at a different mark on a 0.3 mL barrel than on a U-100.

What is CJC-1295?
CJC-1295 is a synthetic analogue of growth-hormone-releasing hormone (GHRH). The 'with DAC' (Drug Affinity Complex) form has an extended half-life via covalent albumin binding; the 'without DAC' form (Mod-GRF 1-29) has a half-life of approximately 30 minutes and is dosed more frequently. It is commonly stacked with ipamorelin.

Frequently asked questions
- CJC-1295 with DAC vs. without DAC?
- With DAC has a half-life of approximately 6–8 days and is dosed weekly or twice weekly. Without DAC (Mod-GRF 1-29) has a 30-minute half-life and is dosed two to three times daily.
- How does CJC-1295 stack with ipamorelin?
- GHRH (CJC-1295) and a GH secretagogue (ipamorelin) act on different receptors and are commonly co-administered to amplify the GH pulse. They are typically reconstituted in separate vials and either co-drawn or alternated.
