CJC-1295 dosage chart by version

Two different compounds are sold under this name. One has DAC, short for drug affinity complex, an add-on that lets it cling to a blood protein and last about a week, and the other doesn't. The chart keeps them in separate rows because a number from one doesn't work for the other. Check which version your vial is before you read an amount, and read the source column too. Background on what CJC-1295 is lives on the CJC-1295 page, and the CJC-1295 with DAC vs. without DAC comparison sets the two versions side by side.

CJC-1295 is sold as a freeze-dried powder for injection under the skin, in 2 mg and 5 mg vials, according to the peptide page, and a 10 mg vial is worked through below in case you find one. You mix it with bacteriostatic water, which is sterile water with a preservative so one vial can be drawn from more than once. The tables show the units to draw on a U-100 syringe, which holds 100 units in 1 mL, for 1, 2 and 3 mL of water.

The unit trap. The DAC amounts are in milligrams and the no-DAC amount is in micrograms, and 100 mcg is a tenth of a milligram. A vial of either looks the same, so the version on the label decides which table to read.

A few units is hard to read on a syringe, so for the no-DAC amounts more water makes each draw bigger and easier to measure. For the DAC amounts, 1 or 2 mL keeps the draw under one syringe.

For a 2 mg or 10 mg vial, or any other water or amount, the reconstitution calculator does the same math.

The DAC version, once a week. In the first human study a single injection raised growth hormone for six days or more and a related growth signal called IGF-1 for 9 to 11 days, and the estimated half-life was 5.8 to 8.1 days. That is why vendor pages give it weekly, or in two halves a week. Neither study tested daily dosing.

The no-DAC version, before sleep. Vendor pages give 100 mcg once a night, on an empty stomach. We found no human study of this version and no label, so the amount and timing are convention.

Twelve weeks, then a break. Twelve weeks on and 4 or more weeks off is the course described most often on vendor pages for both versions. The longest human study ran 7 weeks, and we found nothing published that sets a break.

The first study dosed by body weight and found 30 and 60 mcg per kg particularly well tolerated, which is 13.6 or 27.2 mcg per pound. A 150 pound adult is about 2.0 mg and 4.1 mg, and a 180 pound adult about 2.4 mg and 4.9 mg. The vendor figure of 2 mg is at the low end for a 147 pound adult and falls below it for anyone heavier, and it wasn't sized to anyone's weight.

A mixed vial goes on a 28-day clock in the fridge the day water goes in, however much of it gets used. On the DAC version at 2 mg a week, a 5 mg vial gives two doses with 1 mg left, and a 10 mg vial gives four inside the 28 days, with 2 mg left to expire because the fifth dose would land on the day the vial expires. For 12 weeks that is 12 doses and 24 mg, which takes six 5 mg vials or three 10 mg vials mixed one at a time, about 30 mg bought.

On the no-DAC version at 100 mcg a night, a 5 mg vial holds 50 doses but only 28 fit inside the clock, so about 2.2 mg expires. Twelve weeks is 8.4 mg, which is three 5 mg vials.

Vendor pages most often pair the no-DAC version with ipamorelin, a second compound that works on growth hormone through a different receptor, dosed together before sleep as one blend or two injections. The reasoning on those pages is that the short no-DAC pulse fits ipamorelin's short action, while a signal that lasts a week doesn't fit that pairing. We found no study of the two together. The CJC-1295 ipamorelin dosage page covers the combined amounts and the units to draw.

These are reported experiences. The first human study reported no serious adverse reactions, and neither study covered long courses.

Puffy hands or feet. People report water retention in the hands, feet or face, and if it carries on they usually drop to a smaller amount or stop.

Numb or tingling hands. People report it, sometimes with joint aches, and it's a common reason given on community pages for stopping a course.

Redness or lumps where you inject. People on community pages report it more often on the daily no-DAC schedule, and they rotate the spot or stop if it doesn't settle.

Nothing after 12 weeks. People often stop here. Studies measured growth hormone and IGF-1 in blood, not how anyone looked or felt, so a defined stretch with a decision at the end is the usual way to judge it.
