Example ModGRF 1-29 (CJC-1295 No DAC) Titration Schedule
| Item | Details |
|---|---|
| Dose | 100–300 mcg per injection |
| Frequency | 2–3× per day, fasted (pre-bed key) |
| Timing | ≥2 h after meals; carbs blunt GH |
| Cycle | 12–16 weeks on / 4–8 off |
100 mcg approximates pituitary-receptor saturation per pulse — frequency matters more than dose size. No standalone human trials of the no-DAC form exist; all human pharmacokinetics come from the DAC variant.

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.
ModGRF 1-29 (CJC-1295 No 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
It's the short-acting version of CJC-1295, a GHRH analogue that prompts your body to release its own growth hormone. "No-DAC" means it lacks the Drug Affinity Complex, so it clears in minutes rather than lasting a week — this version is also called mod GRF 1-29. The DAC version is the long-acting, weekly one; No-DAC is the short, frequent one. It is not an approved medicine.
This is the opposite of the DAC version. Because it lasts only minutes, No-DAC is used daily — often once to a few times a day, and timing matters: research protocols favour an empty stomach (food raises insulin and blunts the GH pulse), commonly before bed. If a protocol says "twice weekly," that's the DAC version, not No-DAC. These are research patterns for reference, not a recommendation.
Add bacteriostatic water slowly down the side of the vial and swirl gently until clear — never shake. The water volume sets the concentration: a 5 mg vial with 2 mL gives 2.5 mg/mL, so a 100 mcg measurement is 0.04 mL (4 units on a 1 mL insulin syringe). Since doses are small, a moderate concentration makes them easier to read. The calculator highlights the cleanest unit matches.
These two are very commonly studied together because No-DAC's short pulse pairs with ipamorelin's, but they're still two separate compounds — not one combined number. Calculate each on its own: enter the CJC-1295 amount here and ipamorelin separately. Whether they're drawn into one syringe and how they're timed is a clinical decision, not something a calculator should merge.
It's not a steroid — it's a peptide that signals growth hormone release, a different class entirely 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 it 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.
