CJC-1295 With DAC 5mg Reconstitution: A Step-by-Step Guide

To reconstitute CJC-1295 with DAC 5mg, add bacteriostatic water slowly down the inside wall of the vial — 1 mL to 2.5 mL is typical for a 5 mg vial — then swirl gently until the powder dissolves completely. A 2 mL dilution produces 2,500 mcg per mL, which is easy to measure on a U-100 insulin syringe. Never shake the vial, and refrigerate the mixed solution at 2–8 °C.

What a 5mg CJC-1295 With DAC Vial Contains

CJC-1295 is a growth hormone–releasing hormone (GHRH) analog. The "DAC" stands for drug affinity complex, a modification that lets the peptide bind to albumin and remain in circulation far longer than unmodified GHRH. That difference is why the DAC version is studied on weekly or twice-weekly schedules rather than several times a day.

Most cjc-1295 with dac 5mg product ships as a lyophilized powder inside a sealed glass vial, with the peptide amount printed on the label. These vials are sold as research chemicals, not as drugs. CJC-1295 with DAC is not FDA-approved for human use in the United States.

Supplies You Need

• One 5 mg lyophilized CJC-1295 with DAC vial
• Bacteriostatic water (0.9% benzyl alcohol), 10 mL or 30 mL vial
• Alcohol swabs and clean gloves
• A sterile syringe with an 18–25 gauge mixing needle
• U-100 insulin syringes with 29–31 gauge needles for drawing measured volumes
• A sharps container

Step-by-Step CJC-1295 With DAC Reconstitution

Work on a clean, uncluttered surface and let both vials sit at room temperature for 10 to 15 minutes before starting cjc-1295 with dac reconstitution. Cold glass and cold diluent slow dissolution and encourage clumping.

1. Wash your hands and put on gloves. Wipe the counter with an alcohol pad.
2. Remove the plastic caps from the peptide vial and the water vial, then swab both rubber stoppers with fresh alcohol swabs and let them air-dry for about 10 seconds.
3. Attach a mixing needle to a sterile syringe and draw your chosen volume of bacteriostatic water — for example, 2 mL.
4. Insert the needle into the peptide vial at a slight angle so the tip rests against the glass wall instead of the powder.
5. Push the plunger slowly and let the water run down the glass. Rushing this step creates foam and can damage the peptide.
6. Withdraw the needle and cap it safely, then swirl the vial gently between your fingers or roll it between your palms.
7. Keep swirling until the solution is clear with no visible particles. Do not shake the vial.
8. Write the date and the final concentration on the label, then refrigerate the vial.

Concentration and Draw Volume

The volume of diluent you add sets the concentration, and concentration determines how much liquid you draw for a given amount of peptide. The chart below assumes a full 5 mg vial.

Bacteriostatic water added	Concentration	Volume for 500 mcg	Volume for 1,000 mcg
1 mL	5,000 mcg/mL	0.10 mL (10 units)	0.20 mL (20 units)
2 mL	2,500 mcg/mL	0.20 mL (20 units)	0.40 mL (40 units)
2.5 mL	2,000 mcg/mL	0.25 mL (25 units)	0.50 mL (50 units)
5 mL	1,000 mcg/mL	0.50 mL (50 units)	1.00 mL (100 units)

On a U-100 insulin syringe, 100 units equals 1 mL, so 20 units is 0.2 mL. A larger dilution volume makes small adjustments easier to measure accurately, but it also means more liquid per draw.

Bacteriostatic Water vs. Other Diluents

Diluent	Preservative	Typical use
Bacteriostatic water	0.9% benzyl alcohol	Multi-dose vials; the standard choice for peptide research
Sterile water for injection	None	Single-use only; discard any leftover liquid
0.9% sodium chloride	None unless preserved	Acceptable for some peptides, but stability varies

Bacteriostatic water is preferred because the benzyl alcohol preservative discourages bacterial growth in a vial that gets punctured more than once. Sterile water without a preservative must be treated as single-use.

Storage and Shelf Life After Mixing

• Keep the reconstituted vial refrigerated at 2–8 °C and protected from light.
• Most lab guidance suggests using a mixed vial within about 4 to 6 weeks.
• Store unreconstituted powder frozen and dry, and limit freeze-thaw cycles.
• Never freeze a reconstituted vial; ice crystal formation damages the peptide.
• Discard the solution if it turns cloudy, changes color, or shows particles.

How Much CJC-1295 With DAC Is Used in Research?

Published human research on CJC-1295 with DAC used 30 mcg/kg or 60 mcg/kg given subcutaneously once weekly for six weeks and reported dose-dependent increases in IGF-1. Those figures come from a supervised clinical study and are not self-dosing instructions. Comparing cjc-1295 with dac 5mg dosage across forum posts is unreliable, because body weight, IGF-1 response, and injection timing all change the outcome.

The question "how much cjc 1295 with dac should i take" can only be answered by a licensed clinician who reviews your health history and lab work. This article does not provide a dosing protocol and should not be read as one.

Safety, Purity, and Legal Status

Reported side effects in human studies include injection-site irritation, transient flushing, headache, and IGF-1 changes that may affect fluid balance and blood sugar. Long-term elevation of IGF-1 is a theoretical concern raised in the oncology literature.

Because these products are sold as research chemicals rather than approved drugs, purity varies widely between vendors. Look for a third-party certificate of analysis showing HPLC purity and mass spectrometry confirmation, and confirm that the vendor ships with cold packs.

CJC-1295 with DAC is not FDA-approved for human use, and nothing on this page is medical advice.

Common Reconstitution Mistakes

• Shooting water directly onto the powder, which causes foaming and clumping.
• Shaking the vial instead of swirling it.
• Using diluent straight from the refrigerator.
• Reusing a mixing needle across vials without swabbing the stoppers.
• Skipping the label, then forgetting the concentration weeks later.

COMMON QUESTIONS

Frequently Asked Questions

How much bacteriostatic water should I add to a 5 mg CJC-1295 with DAC vial?

There is no single correct volume. Adding 1 mL, 2 mL, or 2.5 mL to a 5 mg vial are all common choices, producing 5,000 mcg/mL, 2,500 mcg/mL, and 2,000 mcg/mL respectively. Pick the volume that makes your intended measurement easy to read on a U-100 insulin syringe, and write the final concentration on the label.

How long does reconstituted CJC-1295 with DAC last in the refrigerator?

Most lab guidance suggests using a reconstituted peptide within about 4 to 6 weeks when stored at 2–8 °C and protected from light. Lyophilized powder kept dry and frozen can remain stable far longer. Discard the solution if it becomes cloudy or shows visible particles.

What dosage of CJC-1295 with DAC is used in research?

Published human research used 30 mcg/kg or 60 mcg/kg administered subcutaneously once weekly for six weeks, with IGF-1 rising in a dose-dependent pattern. Those amounts come from a supervised clinical study and are not self-dosing instructions. CJC-1295 with DAC is not FDA-approved for human use, so any personal dosing decision belongs with a licensed clinician.
