CJC-1295 Reconstitution Calculator

CJC-1295 comes in two very different versions (with DAC and without). Know which vial you hold, then let the math do the rest.

Mode

Auto picks the cleanest BAC water for you. Manual uses the water you already added.
1

What size is your syringe?

All insulin syringes are U-100, so 100 units equals 1 mL.
2

How much peptide is in your vial?

Check the label on the vial.
3

What is your dose per injection?

Select or enter the amount you want per shot.

    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

    Common questions

    Does this calculator care whether my CJC-1295 has DAC?
    The dilution math is identical for both. What changes is the protocol you bring to it. The warning that matters is on you: confirm which version your vial and your protocol are talking about.
    How much water for a 2 mg vial dosed at 100 mcg?
    With 2 mL of BAC water, 100 mcg lands at a 10 unit draw, clean and readable. One vial holds twenty doses at that rate.
    My blend vial says 10 mg total. What do I enter?
    Enter 10 mg as the vial content and your total combined dose per injection. The calculator treats the blend as one pool, which matches how the ratio was fixed at manufacture.
