CJC-1295 Dosage Chart (2026): Weekly Schedule, Titration and Syringe Units
CJC-1295 dosage chart: the two molecules sold under one name, dosed about twenty times apart. The no-DAC version runs daily in micrograms, the DAC version weekly in milligrams, and the units below are what each injection reads as on a U-100 insulin syringe for the two common vial sizes.
| Week | Dose | Units on a U-100 syringe, 5 mg vial in 2 mL (2.5 mg/mL) | Units on a U-100 syringe, 2 mg vial in 1 mL (2 mg/mL) | Notes |
|---|---|---|---|---|
| Without DAC, weeks 1 to 2 | 50 mcg daily | 2 | 2.5 | Entry dose; evening, fasted, aligned with the natural GH pulse |
| Without DAC, weeks 3 to 12 | 100 mcg daily, or 3 to 5 times a week | 4 | 5 | The usual working dose; commonly paired with 100 mcg ipamorelin in the same syringe |
| With DAC, standard | 2 mg once weekly | 80 | 100 | Long-acting version, half-life over 8 days; day of the week matters less than consistency |
| With DAC, aggressive | 2 mg twice weekly | 80 | 100 | Sustained rather than pulsatile GH signal; water retention is reported more often |
Units on your syringe: the two unit columns assume the vial and water shown in each heading, and a U-100 insulin syringe where 100 units is 1 mL. For any other vial size or water volume, the CJC-1295 calculator on peptulator.com gives the exact mark for your mix.
CJC-1295 dosing is the compound people most often get wrong, and almost always for the same reason: there are two different molecules sold under the same name, and they are dosed roughly twenty times apart. Using the with-DAC version on a without-DAC schedule produces a dose far too small to do anything, which is the single most common error in this corner of the niche.

There are two versions: CJC-1295 with DAC and CJC-1295 without DAC. DAC stands for Drug Affinity Complex, which is basically a molecular modification that extends half-life.
This distinction matters for dosing, timing, and effectiveness.
CJC-1295 Without DAC
This is the shorter-acting version, half-life of about 30 minutes.

Answer five questions about your goal, experience and budget and the Stack Builder shows you a matched research protocol on screen, with the compounds, cycle shape and vendor picks from the six vendors we score.
Build your stack, 2 minutesDosing:
- Standard: 50-100mcg per injection
- Frequency: Daily, or 3-5 times per week
- Timing: Can be done anytime, but evening is optimal (aligns with natural GH pulse)
The without-DAC version, which is the one usually meant by plain CJC-1295, is typically dosed at 100mcg daily. With a 10mg vial reconstituted in 1mL, that is 0.01mL, a small volume that is readable on a 100 unit insulin syringe and very difficult to measure on a 1mL luer syringe. The CJC-1295 calculator does the conversion.
What is commonly reported: changes in sleep quality within the first week or two, then recovery and energy over the following month, with effects building over roughly three to four weeks and then levelling. Growth hormone output is pulsatile and most of it happens during deep sleep, which is why sleep is the effect most consistently described first. None of this has been measured against placebo in a trial of this compound.
Stacking. CJC-1295 without DAC is most often paired with ipamorelin, and the pairing has a real pharmacological rationale rather than a marketing one. CJC-1295 is a GHRH analogue that raises the amplitude of a pulse; ipamorelin is a ghrelin receptor agonist that triggers one. They act on different receptors toward the same output, which is why they are dosed together at the same frequency, commonly 100mcg of each. See the CJC-1295 and ipamorelin stack.

CJC-1295 With DAC
This is the long-acting version, half-life of 8+ days.
Dosing:
- Standard: 2mg per injection
- Frequency: Once weekly, sometimes twice weekly for more aggressive protocols
- Timing: Day of week doesn't matter much due to long half-life, but consistency helps
This is a much larger dose per injection because it's long-acting. The molecule is modified to last longer in your bloodstream, so you use it less frequently but in larger amounts.
The with-DAC version attaches a drug affinity complex that binds albumin, extending the half-life from minutes to days. That converts a daily injection into a weekly or twice weekly one, and it also changes the pharmacology in a way that matters.
What is reported: little in the first day or two, then effects similar to the without-DAC version appearing around day three or four and sustaining. Convenience is the obvious advantage. The trade-off is the reason many people prefer the shorter acting version: a sustained elevation in growth hormone releasing signal flattens the natural pulsatile pattern, and that pattern is thought to matter for how the signal is received.
Subcutaneous water retention is more commonly reported with the DAC version than with the daily one, which is consistent with a sustained rather than pulsatile signal. It is generally described as mild and as resolving after discontinuation.

The CJC + Ipamorelin Stack
This is probably the most popular peptide stack for growth hormone optimization. Both stimulate GH but through different pathways. The Bureau's best stack for muscle growth guide runs through it in three tiers with real vendor costs.
CJC-1295 (without DAC) at 100mcg plus Ipamorelin at 100mcg, both daily, is the standard approach. Some people do it as a single injection of both mixed together. Others keep them separate for flexibility.
CJC-1295 and ipamorelin are commonly drawn into the same syringe, at 100mcg of each, which at standard reconstitution is 0.01mL of each. Mixing two reconstituted peptides in one syringe immediately before injection is routine practice; storing them pre-mixed is not, since stability of the combination has not been established.
Results after 8 weeks: Noticeable improvement in recovery, energy, sleep quality, and subtle improvements in body composition (less fat, more muscle, despite no diet change). These are indirect GH effects.
The Three Dosing Mistakes That Account for Most Failures
Mistake 1: dosing the DAC version like the no-DAC version. 100mcg weekly of the with-DAC form does essentially nothing. The with-DAC protocols in circulation use roughly 2mg per administration. This is the error behind most reports that CJC-1295 did not work.

Open the CJC-1295 calculator peptulator.com, the Bureau's independent toolMistake 2: getting the reconstitution arithmetic wrong. At these dose sizes the difference between 0.01mL and 0.1mL is a tenfold error and both are easy to misread on the wrong syringe. Use a 100 unit insulin syringe and run the numbers through a calculator rather than doing them from memory.
Mistake 3: stacking CJC-1295 and ipamorelin on different schedules. The rationale for the pairing is that both act on the same pulse. Running one daily and the other three times a week gives up most of the reason for combining them.
Sourcing Quality CJC-1295
Quality vendors carry CJC-1295 in both versions. Quality is important and pricing is reasonable ($60-$120 monthly for the without-DAC version at 100 mcg one to three times daily, list prices checked 2026-09-08; $200-$350 for the with-DAC version).
The key is making sure you're getting the right version. Some vendors label it clearly, some don't. Confirm before ordering.

Amino Club PSPeptides Limitless Life PeptidesFrequently Asked Questions
How many units is 100 mcg of CJC-1295 on an insulin syringe?
100 mcg is 0.1 mg. A 5 mg vial in 2 mL of bacteriostatic water is 2.5 mg/mL, so 0.1 mg is 0.04 mL, which reads as 4 units on a U-100 syringe. A 2 mg vial in 1 mL is 2 mg/mL and the same dose is 5 units. Those are small draws, so adding more water to the vial makes the dose easier to read without changing how much peptide you inject. The chart at the top of this page covers both versions of the compound.
What is the standard CJC-1295 dosage?
It depends entirely on which version you have. CJC-1295 without DAC is typically run at around 100 mcg per injection, once or twice daily, because it clears quickly and is dosed to mimic a pulse. CJC-1295 with DAC lasts far longer and is typically run at a much lower weekly frequency, often once or twice a week.
What is the difference between CJC-1295 with and without DAC?
DAC stands for drug affinity complex, an addition that binds the peptide to albumin and extends its half life from minutes to days. Without DAC, the compound produces a short pulse. With DAC, it produces a sustained elevation, which is a genuinely different physiological pattern and is why the two cannot share a dosing schedule.
Should CJC-1295 be stacked with ipamorelin?
It very commonly is. The two act on different receptors, so the combined growth hormone response is larger than either produces alone. The no-DAC version is the one usually paired with ipamorelin, because both are short acting and can be given in the same injection.
When is the best time to inject CJC-1295?
Most protocols inject on an empty stomach, often before bed, since food blunts the growth hormone response and the largest natural pulse happens in early sleep. This reasoning comes from growth hormone physiology rather than from a trial comparing injection times.
How do you convert a CJC-1295 dose to syringe units?
Divide the vial strength by the bacteriostatic water added to get the concentration, then divide your dose by that concentration and multiply by 100 for a U-100 syringe. A 5 mg vial in 2 mL gives 2.5 mg/mL, at which 100 mcg reads as 4 units, which is low enough that adding more water is usually the better choice.
