CJC-1295 (with DAC) reconstitution calculator
Long-acting GHRH(1-29) analog bearing a Drug Affinity Complex (DAC) that covalently binds serum albumin, extending half-life to ~6-8 days versus minutes for native GHRH. In healthy adults, single subcutaneous doses raised growth hormone and IGF-1 for roughly 6-11 days (Teichman, J Clin Endocrinol Metab 2006, PMID 16352683). Sold as a research chemical with no approved human therapeutic indication and no long-term safety data. Distinct from the shorter-acting modified GRF(1-29)/ipamorelin blend. Weekly research dosing figures are community practice, not label-derived.

Frequently asked questions
How much bacteriostatic water should I add to CJC-1295 (with DAC)?
For a 2mg vial of CJC-1295 (with DAC), add 2ml of bacteriostatic water. This concentration works well with a standard insulin syringe.
What is the typical CJC-1295 (with DAC) dosage?
Typical research dosages for CJC-1295 (with DAC) range from 500 to 2000 mcg, administered 1-2x weekly.
How long does reconstituted CJC-1295 (with DAC) last?
Reconstituted CJC-1295 (with DAC) should be stored at 2-8°C refrigerated and used within 28 days. Unreconstituted vials can be stored for up to 24 months.
How do I calculate my CJC-1295 (with DAC) dose?
Divide your target dose by the concentration to get the volume, then multiply by 100 for units on a U-100 insulin syringe. For example, a 2mg vial in 2ml of bacteriostatic water gives 1000 mcg/ml. The calculator above does this automatically once you enter your vial size, water volume, and desired dose.
How many units of CJC-1295 (with DAC) should I draw on an insulin syringe?
On a U-100 insulin syringe, 1 unit equals 0.01 ml regardless of the barrel size (0.3ml, 0.5ml, or 1ml). Enter your reconstitution details in the calculator to see the exact number of units to draw for your dose.
