CJC 1295 no DAC reconstitution explained: how much bacteriostatic water to use, storage tips, dosing basics, and safety notes for research use only.
Reconstituting CJC 1295 no DAC means adding bacteriostatic water to a vial of freeze-dried (lyophilized) peptide so it can be measured and drawn with a syringe. In most cases you add 1 to 2 mL of bacteriostatic water to a 2 mg vial, which creates a concentration of 1,000 to 2,000 mcg per mL. Swirl the vial gently instead of shaking it, then refrigerate it right away at 2–8 °C (36–46 °F).
CJC-1295 without DAC is sold as a research chemical only. It is not FDA-approved for human use in the United States, and the information below is not medical advice.
What No DAC Means for Mixing and Storage
The DAC in CJC-1295 stands for Drug Affinity Complex, a chemical tag that binds the peptide to albumin in the bloodstream and stretches its activity over several days. Without that tag, the molecule — commonly labeled modified GRF (1-29) — is cleared much faster.
The practical difference shows up in two places: how often the vial is drawn from and how carefully it is stored. Any comparison of cjc-1295 dac vs no dac shows that the no-DAC version gets more attention to cold chain and light exposure because the peptide is less stable once it is in solution.
Supplies You Need Before You Start
- Lyophilized CJC-1295 no DAC vial
- Bacteriostatic water (sterile water with 0.9% benzyl alcohol)
- 70% isopropyl alcohol swabs
- U-100 insulin syringes, 29–31 gauge
- Sharps container and a clean, dedicated work surface
Bacteriostatic water is the standard choice because the benzyl alcohol slows bacterial growth after the rubber stopper has been punctured several times. Plain sterile water works for a single-use vial, but that solution should be used quickly and then discarded.
Step-by-Step CJC 1295 No DAC Reconstitution
A typical cjc-1295 no dac reconstitution uses 1 mL of bacteriostatic water per 2 mg vial, though 2 mL is also common when smaller draw volumes are easier to measure.
- Wipe both stoppers with an alcohol swab and let them air-dry for about 10 seconds.
- Draw your chosen volume of bacteriostatic water into the syringe.
- Insert the needle into the peptide vial at an angle and aim the stream at the glass wall rather than directly at the powder.
- Push the plunger slowly. Fast spraying can damage the peptide and create foam.
- Withdraw the needle and swirl the vial between your fingers until the powder is fully dissolved. Do not shake it.
- Write the reconstitution date on the label and refrigerate the vial immediately.
The lyophilized powder itself is stable in a freezer for months, but once water is added the clock starts. Light and warmth break the peptide down faster, so a covered box in the main refrigerator body is better than the door shelf.
How to Calculate Your Dose Volume
Dose volume depends entirely on how much water you added. The table below assumes a 2 mg (2,000 mcg) vial and a U-100 insulin syringe, where 100 units equal 1 mL.
| Bacteriostatic water added | Concentration | 10 units (0.1 mL) contains |
|---|---|---|
| 1 mL | 2,000 mcg/mL | 200 mcg |
| 2 mL | 1,000 mcg/mL | 100 mcg |
| 2.5 mL | 800 mcg/mL | 80 mcg |
| 3 mL | about 667 mcg/mL | about 67 mcg |
Reconstitution changes the concentration of a peptide, not its identity. A 2 mg vial still holds 2 mg of CJC-1295 no DAC whether it is mixed with 1 mL or 3 mL of water.
Published cjc-1295 no dac dosage ranges in research summaries usually fall between 100 mcg and 300 mcg per injection, but no regulatory agency has approved a human dose. Anyone weighing personal use should discuss it with a licensed healthcare professional.
Storage, Half-Life, and Handling
The cjc 1295 no dac half-life is short, reported at roughly 30 minutes in circulation, because the peptide lacks the albumin-binding tag. The short half-life is a pharmacokinetic detail that does not change the mixing steps, but it does explain why this compound is often studied alongside longer-acting peptides.
Keep reconstituted vials at 2–8 °C, protect them from light, and avoid repeated freeze-thaw cycles. Most researchers discard reconstituted peptide after 2 to 4 weeks.
Safety, Legality, and Common Mistakes
CJC-1295 without DAC is not approved by the FDA for human use, and product purity varies widely between suppliers. Certificates of analysis are worth reviewing before any purchase.
- Shaking the vial, which can shear the peptide and create foam
- Using tap water or irrigation saline instead of bacteriostatic water
- Freezing a vial after reconstitution
- Reusing needles or skipping alcohol swabs
Reported side effects in user accounts include redness at the injection site, flushing, headache, and numbness or tingling in the hands. People with hormone-sensitive conditions or anyone taking prescription medication should consult a physician before considering use.
Comparisons with other compounds come up constantly, and tesamorelin vs cjc-1295 no dac is a frequent search because both are growth-hormone-releasing peptides. Forum threads often blend personal experience with speculation, so anecdotal reports should not be treated as clinical evidence.
Frequently Asked Questions
How much bacteriostatic water should I add to a 2 mg CJC 1295 no DAC vial?
Most people add 1 to 2 mL of bacteriostatic water to a 2 mg vial. Adding 1 mL produces 2,000 mcg per mL, while 2 mL produces 1,000 mcg per mL, so the amount only changes how many units you draw per dose. Either volume dissolves the powder completely as long as the vial is swirled and not shaken.
How long does reconstituted CJC 1295 no DAC last in the refrigerator?
Stored at 2–8 °C and protected from light, reconstituted peptide is commonly used within 2 to 4 weeks. The benzyl alcohol in bacteriostatic water slows bacterial growth, but it does not stop peptide degradation. Vials that look cloudy or contain particles should be discarded.
Is CJC 1295 no DAC FDA-approved for human use?
No. CJC-1295 without DAC is not FDA-approved for human use in the United States and is sold strictly as a research chemical. Products from different suppliers vary in purity, and no approved human dose exists. Anyone considering personal use should talk with a licensed healthcare professional first.
