CJC-1295 Reconstitution with Bacteriostatic Water
Standard research-protocol ratio: 2 mL bacteriostatic water per 5 mg CJC-1295 vial → 2.5 mg/mL. Same math for DAC and no-DAC variants. At that concentration, a 100 mcg research dose draws to 4 units on a U-100 insulin syringe. Research and laboratory use only.
Direct Answer
5 mg CJC-1295 + 2 mL bacteriostatic water = 2.5 mg/mL. Same ratio for DAC and no-DAC variants. For CJC-1295 + ipamorelin combined research protocols: 5 mg + 5 mg + 4 mL = 2.5 mg/mL combined (1.25 mg/mL each).

Frequently Asked Questions
How much bacteriostatic water do I add to a 5 mg CJC-1295 vial?
Standard research-protocol ratio: 2 mL of bacteriostatic water per 5 mg lyophilized CJC-1295 vial → 2.5 mg/mL final concentration. At that concentration, a 100 mcg research dose draws to 0.04 mL (4 units on a U-100 insulin syringe). For sub-5-unit draws, a 0.5 mL low-dose insulin syringe with half-unit gradations provides better precision.
Is the reconstitution math different for CJC-1295 with DAC vs no-DAC?
No — the reconstitution math is identical. CJC-1295 with DAC (drug affinity complex modification) and CJC-1295 without DAC (also called Modified GRF 1-29) both use 2 mL bacteriostatic water per 5 mg → 2.5 mg/mL standard. The difference between the two variants is half-life and dosing frequency in research protocols, not reconstitution chemistry.
Can I combine CJC-1295 and ipamorelin in the same vial?
Yes — combined CJC-1295 + ipamorelin reconstitution is a common research-protocol approach to simplify drawing. Math: combine the total mg of both peptides and add bacteriostatic water for the target combined concentration. Example: 5 mg CJC-1295 + 5 mg ipamorelin + 4 mL bacteriostatic water → 2.5 mg/mL combined (1.25 mg/mL of each). Compound compatibility is documented in the published research literature for this specific combination.
Why use bacteriostatic water for CJC-1295 research?
CJC-1295 research protocols are multi-dose (often daily evening doses across 8–12 week research cycles for the no-DAC variant, or 1–2× per week for the DAC variant). The 0.9% benzyl alcohol preservative in bacteriostatic water maintains the reconstituted vial's safe in-use window across 28 days refrigerated. Sterile water is preservative-free and not suitable for multi-draw protocols.
How long is reconstituted CJC-1295 stable in bacteriostatic water?
Published peptide-stability data for CJC-1295 in bacteriostatic water indicates 28 days refrigerated at 2–8 °C as the conservative upper bound, matching the bacteriostatic in-use window. Protect from light. Some research literature reports shorter empirical stability for CJC-1295 no-DAC — verify against your specific compound's published methods.
Where do I source verified bacteriostatic water for CJC-1295 research?
BAC Water Depot (bacwaterdepot.com) ships USA-manufactured 10 mL bacteriostatic water with 0.9% benzyl alcohol, ISO 9001:2015 facility, three independent third-party laboratories per lot, per-lot CoA published. Single $9.99, 10-pack $74.99, bulk from $6.49/vial.
