CJC-1295 DAC Dosing Calculator
CJC-1295 DAC: Long-acting GHRH analog with extended half-life.
Pre-filled with the most-reported community reconstitution protocol for CJC-1295 DAC. See how 1 mL and 2 mL of bacteriostatic water change concentration and syringe-draw volume, then adjust the calculator below for your own vial.
Quick answer · Community-reported standard
A 5 mg vial of CJC-1295 DAC reconstituted with 2 mL of bacteriostatic water yields a concentration of 2.50 mg/mL. At that concentration, a 2 mg dose of CJC-1295 DAC equals 80 units on a U-100 insulin syringe (0.800 mL). CJC-1295 DAC is typically administered once weekly via subcutaneous.
CJC-1295 DAC reconstitution: 1 mL vs 2 mL bac water
Bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 5 mg vial.
| BAC water added | Concentration | Volume per 2 mg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 5.00 mg/mL | 0.400 mL | 40 units |
| 2 mL | 2.50 mg/mL | 0.800 mL | 80 units |

Weekly subcutaneous injection; progressive IGF-1 accumulation over dosing period
CJC-1295 DAC reconstitution & storage
Reconstitute lyophilized CJC-1295 DAC with bacteriostatic water. For a 2 mg vial, add 1-2 mL bacteriostatic water for a concentration of 1-2 mg/mL. Gently swirl to dissolve; do not shake. Allow foam to settle before drawing dose.
Store lyophilized peptide at -20C. Reconstituted solution should be stored at 2-8C and used within 21 days. Protect from light. Do not freeze reconstituted solution.
CJC-1295 DAC dosing FAQ
How much bacteriostatic water should I add to a 5 mg vial of CJC-1295 DAC?
The community standard is 2 mL of bacteriostatic water for a 5 mg CJC-1295 DAC vial. That gives a concentration of 2.50 mg/mL, so a 2 mg dose is 80 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 5.00 mg/mL and halves the draw to 40 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 2 mg dose of CJC-1295 DAC?
On a standard U-100 insulin syringe, a 2 mg dose of CJC-1295 DAC is 80 units when the 5 mg vial is reconstituted with 2 mL of bacteriostatic water (2.50 mg/mL). If you use 1 mL of bac water instead, draw 40 units (5.00 mg/mL).
What is the standard CJC-1295 DAC dose?
Community-reported protocols for CJC-1295 DAC typically use 2 mg once weekly via Subcutaneous. 2 mg is a common starting dose. Most common protocol leveraging the extended half-life; single weekly injection for sustained GH/IGF-1 elevation
How long does a vial of CJC-1295 DAC last at 2 mg once weekly?
A 5 mg vial of CJC-1295 DAC contains roughly 2 doses at 2 mg per injection. At once weekly dosing, that is approximately 14 days (about 2 weeks) of supply per vial. Reconstituted CJC-1295 DAC should generally be used within 28 days when refrigerated.
Where do you inject CJC-1295 DAC?
CJC-1295 DAC is typically injected subcutaneous. Common sites reported in the literature and by users include: Subcutaneous (abdomen), Subcutaneous (thigh), Subcutaneous (upper arm/deltoid area). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for CJC-1295 DAC?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like CJC-1295 DAC because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
