Reconstitution chart: 2 mg vial
| BAC water added | Concentration | Draw for 100 mcg dose | Draw for 200 mcg dose |
|---|---|---|---|
| 1 mL | 2,000 mcg/mL | 5 units | 10 units |
| 1.5 mL | 1,333 mcg/mL | 7.5 units | 15 units |
| 2 mL | 1,000 mcg/mL | 10 units | 20 units |
| 2.5 mL | 800 mcg/mL | 12.5 units | 25 units |
Draws are U-100 insulin syringe units (100 units = 1 mL). Formula: dose in mcg ÷ (vial mcg ÷ water mL) × 100. The calculator above handles any other combination.
About CJC-1295
CJC-1295 is a synthetic analog of growth-hormone-releasing hormone (GHRH). It exists in two forms that get confused constantly: CJC-1295 with DAC, where a drug affinity complex extends the half-life to about a week, and CJC-1295 without DAC (also sold as Mod GRF 1-29), which clears in under 30 minutes. Neither form has regulatory approval. The two are NOT interchangeable, and protocols written for one are wrong for the other.
Community protocols for the no-DAC version typically discuss 100 to 300 mcg taken one to three times daily, often before bed to ride the natural growth hormone pulse. The DAC version is discussed in larger, less frequent amounts because it stays active for days. Before you calculate anything, read your vial label and your protocol twice to confirm which version both refer to.
CJC-1295 is most often discussed in combination with ipamorelin, a secretagogue that works through a different receptor, and many vendors sell pre-mixed blend vials. For a blend vial, enter the combined peptide content printed on the label and your combined dose; the dilution math is identical. A 2 mg vial at 100 mcg per dose holds twenty doses, so small vials go further than they look.
Quick facts
- Status: no regulatory approval (either version)
- With DAC: half-life around 6 to 8 days. Without DAC (Mod GRF 1-29): under 30 minutes
- Community-discussed no-DAC range: 100 to 300 mcg, one to three times daily
- Common vial sizes: 2 and 5 mg; often blended with ipamorelin
