CJC-1295 (no DAC) Calculator

CJC-1295 (no DAC) dosage calculator

The CJC-1295 (no 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 (no 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 modified GHRH analog that binds to pituitary GHRH receptors to stimulate pulsatile growth hormone release. Enter your target dose in the calculator above to see the exact number of units to draw.

CJC-1295 (no DAC) and GHRH peptides

CJC-1295 (no DAC) is a Modified GHRH (1-29) analog. A modified GHRH analog that binds to pituitary GHRH receptors to stimulate pulsatile growth hormone release. Other peptides in the GHRH class include CJC-1295 with DAC , Sermorelin , and Tesamorelin .

CJC-1295 without DAC — sometimes called "Mod GRF (1-29)" or "modified GRF" — is a synthetic analog of the first 29 amino acids of growth hormone releasing hormone (GHRH) with amino acid substitutions that increase stability relative to native GHRH. Published research has studied the molecule for its ability to stimulate pulsatile growth hormone release from the anterior pituitary. It is structurally distinct from CJC-1295 with DAC (drug affinity complex), which carries a maleimide group that binds albumin covalently. CJC-1295 (no DAC) is not approved by the FDA for human use. Research-grade material is sold as a laboratory reagent.

How to reconstitute CJC-1295 (no DAC)

Research vendors typically offer CJC-1295 (no DAC) in 2 mg or 5 mg lyophilized vials. Reconstitution with 2–3 mL of bacteriostatic water is commonly reported.

Reconstituting CJC-1295 (no 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 (no 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 (no 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 (no DAC) half-life and storage

Published pharmacokinetic data reports a plasma half-life of approximately 30 minutes for CJC-1295 without DAC — substantially shorter than the albumin-binding DAC variant.

Lyophilized CJC-1295 (no DAC) is typically stored refrigerated at 2–8 °C or frozen for longer storage. Reconstituted solutions are commonly refrigerated and protected from light.

Common CJC-1295 (no DAC) dosing mistakes

Most CJC-1295 (no 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.
