CJC-1295 (With DAC) at a glance

5mg vial + 1mL BAC water = 20 units = 1mg — Frequency: weekly — Best taken: any consistent time

Full CJC-1295 (With DAC) dosing reference — reconstitution per vial size, dose-to-units table, side effects and sources.

What it does

• A longer-acting version of CJC-1295 — the DAC (Drug Affinity Complex) extends its half-life to about a week instead of daily dosing.
• Produces a steadier, more sustained growth hormone elevation than CJC-1295 without DAC.
• Distinct from the No-DAC version already in this app — different dosing schedule and vial math.

Raising growth hormone can unmask previously hidden hypothyroidism and shift how the body converts thyroid hormone — that is documented in hypopituitary patients on growth hormone replacement, not in healthy people using secretagogues, and how often it matters here is unknown. Because DAC keeps GH elevated for about a week per dose, this effect is more sustained than with daily-dosed secretagogues. GH also raises blood sugar, working against insulin and other diabetes medications. Talk to your prescribing doctor before combining, especially if you take thyroid or diabetes medication.

Notes

All vial sizes reconstitute to 5mg/mL (50mcg/unit) so the syringe reads the same regardless of size. Community protocols commonly cycle GH-secretagogue peptides like this one — typically 8-12 weeks on followed by 4 weeks off (up to 12 weeks off after higher-dose runs) — since continuous use may reduce pituitary receptor sensitivity over time. This app defaults to once-weekly use; whether and when to take a break is a question for your prescriber.

Side Effects

• Facial flushing and injection site reactions.
• More water retention than No-DAC — GH stays elevated continuously.
• Headache and fatigue in the first weeks.
• Effects persist longer; each dose lasts about a week.

CJC-1295 (With DAC) vial sizes and concentrations

Standard water for each CJC-1295 (With DAC) vial size in the Dosify Me data, and the concentration it gives. One unit is 0.01 mL on a U-100 insulin syringe.

Worked example for CJC-1295 (With DAC)

1. The example vial: 5 mg of CJC-1295 (With DAC), mixed with 1.00 mL of bacteriostatic water.
2. Concentration: 5 mg ÷ 1.00 mL = 5 mg/mL.
3. One syringe unit is 0.01 mL, so it holds 5 mg/mL × 0.01 mL = 0.05 mg (50 mcg).
4. Example quantity: 1000 mcg = 1 mg.
5. Volume: 1 mg ÷ 5 mg/mL = 0.2 mL.
6. Syringe reading: 0.2 mL × 100 = 20 units.
