Example CJC-1295 DAC Titration Schedule
| Item | Details |
|---|---|
| Standard dose | 1–2 mg SC once weekly |
| Half-life | 5.8–8.1 days (clinical) |
| Cycle | 6–8 weeks on / 4–8 off |
Daily 200–400 mcg dosing contradicts the pharmacology: the albumin-binding DAC gives a 6–8 day half-life, so weekly dosing is the studied pattern. Development was halted in 2006 after a cardiovascular death in the Phase 2 trial.

Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.
- Use clean syringe-unit math before measuring.
Common Mistakes
- Confusing milligrams with milliliters.
- Choosing an option with awkward decimal units.
- Using too little liquid for very small measurements.
- Shaking the vial aggressively.
CJC-1295 DAC Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions
CJC-1295 is a GHRH analogue — it prompts your body to release more of its own growth hormone. The "DAC" (Drug Affinity Complex) is a modification that binds to blood albumin and dramatically extends how long it lasts, from minutes to roughly a week. That's the key difference from "No-DAC" CJC-1295 (also called mod GRF 1-29), which clears within minutes. It is not an approved medicine.
This is where the two versions differ most. Because DAC lasts about a week, research dosing is typically once or twice weekly — not daily. No-DAC (mod GRF 1-29) is the opposite: it's used daily, often multiple times, usually paired with ipamorelin. So if a protocol says "daily," that's the No-DAC version, not DAC. These are research patterns for reference, not a recommendation.
FAdd bacteriostatic water slowly down the side of the vial and swirl gently until clear — never shake. The water volume sets the concentration: a 2 mg vial with 1 mL gives 2 mg/mL, so a 100 mcg measurement is 0.05 mL (5 units on a 1 mL insulin syringe). Since doses are small, a lower concentration makes them easier to read. The calculator highlights the cleanest unit matches.
CJC-1295 and ipamorelin are commonly studied together because they act on growth hormone through different mechanisms, but they're two separate compounds — they aren't merged into one number. Calculate each on its own: enter the CJC-1295 amount here and ipamorelin separately. Note that the long-acting DAC version is paired with ipamorelin less often than No-DAC; how they're combined is a clinical decision, not something a calculator should fuse.
It's not a steroid — it's a peptide that signals growth hormone release, a completely different class from anabolic steroids. It isn't an approved drug, so research-grade quality varies. For storage: keep the reconstituted solution refrigerated at 2–8°C (36–46°F), away from light, and use within a few weeks; sealed powder lasts longest frozen at −20°C. Avoid repeated freeze-thaw cycles.
Practical takeaway: If your goal involves weight management, metabolic health, recovery, physical performance, cognitive function, appearance, or general well-being, discuss it with a licensed healthcare professional. They can help you evaluate approved, evidence-based options rather than relying on an unapproved or investigational compound. This calculator is intended only for transparent research-reference calculations and does not determine an appropriate amount, recommend use, or replace professional medical guidance.
