CJC-1295 with DAC Calculator

CJC-1295 with DAC dosage calculator

The CJC-1295 with DAC dosage calculator above converts a target dose into exact syringe units based on your vial size and how much bacteriostatic water you used to reconstitute it. CJC-1295 with DAC is commonly sold in 2 mg, 5 mg vials. The calculator supports both U-100 and U-40 insulin syringes and flags draws that are too large for the syringe barrel or too small to measure accurately. A long-acting GHRH analog with a drug affinity complex that covalently binds albumin to extend plasma half-life. Enter your target dose in the calculator above to see the exact number of units to draw.

CJC-1295 with DAC and GHRH peptides

CJC-1295 with DAC is a Long-acting GHRH analog with drug affinity complex. A long-acting GHRH analog with a drug affinity complex that covalently binds albumin to extend plasma half-life. Other peptides in the GHRH class include CJC-1295 (no DAC) , Sermorelin , and Tesamorelin .

CJC-1295 with DAC is a long-acting analog of growth hormone releasing hormone (GHRH) that incorporates a drug affinity complex (DAC) — a maleimide functional group that covalently binds circulating albumin. Published pharmacokinetic research reports that this albumin binding dramatically extends the molecule’s plasma half-life compared to native GHRH or the no-DAC variant. It has been studied for its effect on sustained, rather than pulsatile, growth hormone release. CJC-1295 with DAC is not approved by the FDA for human use. Research-grade material is sold as a laboratory reagent only.

How to reconstitute CJC-1295 with DAC

Research vendors typically offer CJC-1295 with DAC in 2 mg or 5 mg lyophilized vials. Reconstitution with 2–3 mL of bacteriostatic water is commonly reported.

Reconstituting CJC-1295 with DAC is the same unit-conversion process used for any lyophilized peptide:

1. Draw your chosen volume of bacteriostatic water into a syringe.
2. Inject the bacteriostatic water slowly down the side of the CJC-1295 with DAC vial — do not shoot it directly onto the powder.
3. Swirl gently until the powder fully dissolves. Do not shake.
4. Store the reconstituted vial refrigerated.
5. To dose, calculate your draw volume: divide your target dose by the concentration (vial mg ÷ water mL = mg/mL). The calculator above does this automatically.

For CJC-1295 with DAC specifically, 2 mg, 5 mg vials are common. A typical reconstitution adds 2 mL of bacteriostatic water, producing a concentration of 2.5 mg/mL for the 5 mg vial size.

CJC-1295 with DAC half-life and storage

Published pharmacokinetic studies report a plasma half-life of approximately 8 days for CJC-1295 with DAC, attributed to the covalent albumin binding.

Lyophilized CJC-1295 with DAC is typically stored refrigerated or frozen for long-term storage. Reconstituted solutions are commonly refrigerated and protected from light.

Common CJC-1295 with DAC dosing mistakes

Most CJC-1295 with DAC draw errors are unit errors, not arithmetic errors: confusing mg with mcg (1 mg = 1,000 mcg), or reading a U-40 syringe with U-100 math — the same printed mark holds 2.5× the volume. Two more worth avoiding: leaving the vial unlabeled, so the concentration and reconstitution date are lost, and under-diluting to the point where the draw is under about one unit and can no longer be read accurately.

Each of these is covered in full in the guides: reconstitution math from first principles, U-100 vs U-40 syringes, storage and shelf life, and how to reconstitute peptides.
