CJC-1295 with DAC 5mg dosage usually falls between 1 mg and 2 mg per week. See reconstitution math, vial duration, stacking, and safety notes.
CJC-1295 with DAC is a long-acting growth hormone-releasing hormone (GHRH) analog sold as a research chemical, and 5 mg is the vial size most suppliers ship. Research protocols generally use about 1 mg to 2 mg per week by subcutaneous injection, because the Drug Affinity Complex (DAC) extends the half-life to roughly six to eight days. A single 5 mg vial therefore covers about two and a half to five weeks of research, depending on the weekly amount used.
What the "5 mg" on the Label Actually Means
A 5 mg vial holds 5 milligrams of lyophilized CJC-1295 with DAC powder. That number describes total quantity, not dose. The dose is whatever volume you draw after reconstitution, so the same vial can be divided into 2, 5, 10, or more individual research doses.
The DAC portion binds the peptide to albumin in the bloodstream, which is why CJC-1295 with DAC stays active for days while modified GRF(1-29) and sermorelin clear within hours. This is the main reason the dosing math differs between them: short-acting GHRH analogs are injected two or three times daily, while CJC-1295 with DAC is injected once or twice per week.
CJC-1295 with DAC is not FDA-approved for human use in the United States and is sold strictly for laboratory research.
Typical CJC-1295 With DAC Dosage Ranges
Most supplier reference sheets and published protocols place the cjc-1295 with dac dosage between 1 mg and 2 mg per week. Some researchers split that into two smaller injections, while others use one weekly injection because the half-life is long enough to sustain activity.
| Weekly amount | Typical frequency | Notes |
|---|---|---|
| 1 mg | Once per week | Common lower-end starting point |
| 1.5 mg | Once or twice per week | Middle of the typical range |
| 2 mg | Once or twice per week | Upper end most protocols stop at |
| 3 mg or more | Not typical | No clear added benefit, more side-effect risk |
Amounts above 2 mg per week are uncommon in the research literature and do not appear to produce proportionally larger growth hormone or IGF-1 responses. In anecdotal reports, larger amounts mainly increase water retention, joint achiness, and fatigue.
Reconstituting a cjc-1295 with dac 5mg Vial
Reconstituting a cjc-1295 with dac 5mg vial determines how many units you draw for each dose, so it is worth doing carefully. The steps below follow the standard laboratory approach.
- Let the vial and the bacteriostatic water reach room temperature.
- Swab both rubber stoppers with an alcohol pad.
- Inject the chosen volume of water slowly down the inside glass wall, not directly onto the powder.
- Swirl gently until fully dissolved. Never shake the vial.
- Refrigerate at 2 to 8 degrees Celsius and protect the vial from light.
Most researchers add 2 mL to 2.5 mL of bacteriostatic water, because that keeps injection volumes small while making the arithmetic easy.
| Water added | Concentration | Volume for 1 mg | Volume for 2 mg |
|---|---|---|---|
| 1 mL | 5 mg/mL | 0.2 mL (20 units) | 0.4 mL (40 units) |
| 2 mL | 2.5 mg/mL | 0.4 mL (40 units) | 0.8 mL (80 units) |
| 2.5 mL | 2 mg/mL | 0.5 mL (50 units) | 1.0 mL (100 units) |
| 5 mL | 1 mg/mL | 1.0 mL (100 units) | 2.0 mL (200 units) |
Unit figures assume a U-100 insulin syringe. At 2 mg/mL, 1 mg equals 0.5 mL, which is 50 units.
5 mg vs 2 mg Vials: Which Size Fits a Protocol
| Vial size | Lasts at 1 mg/week | Lasts at 2 mg/week | Best suited for |
|---|---|---|---|
| 2 mg | 2 weeks | 1 week | Short runs and titration |
| 5 mg | 5 weeks | 2.5 weeks | Standard 8 to 12 week research cycles |
| 10 mg | 10 weeks | 5 weeks | Longer protocols, lower cost per mg |
A single 5 mg vial does not cover a full eight- to twelve-week cycle at 2 mg per week, so most researchers plan on two or three vials for a run of that length.
Stacking: cjc-1295 dac with ipamorelin dosage
CJC-1295 with DAC is often studied alongside ipamorelin, a ghrelin mimetic that triggers growth hormone release through a different receptor. Pairing a GHRH analog with a ghrelin mimetic is thought to create a larger pulse than either compound produces alone.
In these protocols, cjc-1295 dac with ipamorelin dosage usually keeps the CJC-1295 portion at 1 mg to 2 mg per week while ipamorelin is used at 100 mcg to 300 mcg once or twice daily. Ipamorelin clears quickly, so it is often injected on the same day as the weekly CJC-1295 dose or on separate days, depending on the schedule being tested.
Side Effects, Safety, and Legal Status
Because one injection keeps IGF-1 elevated for days, side effects can linger longer than they do with short-acting peptides. Reported effects include:
- Redness, lumps, or mild pain at the injection site
- Water retention and puffiness in the hands and feet
- Joint stiffness or carpal tunnel-like tingling
- Fatigue, headache, and short-term changes in blood sugar
- Unknown long-term effects from sustained GH and IGF-1 elevation
Anyone considering this compound should discuss it with a healthcare professional, and no research chemical should be treated as a substitute for medical care. In the United States, CJC-1295 with DAC is not FDA-approved for human use, it is sold for research only, and it is banned by WADA and most athletic governing bodies.
What Forum Threads and Bodybuilding Boards Add
Search cjc-1295 with dac dosage reddit and you will find users posting injection schedules, bloodwork, and complaints about water weight. The most repeated consensus in those threads is that 1 mg to 2 mg per week is the practical range and that higher amounts mostly add side effects rather than results.
In cjc-1295 with dac dosage bodybuilding discussions, the peptide usually appears as part of a recovery or body-composition stack with ipamorelin or a GHRP, run for eight to twelve weeks. Forum logs are anecdotal, and they frequently involve other compounds, which makes it impossible to attribute any specific result to CJC-1295 with DAC.
Frequently Asked Questions
How long does a 5mg vial of CJC-1295 with DAC last?
A 5 mg vial lasts about five weeks at 1 mg per week and about two and a half weeks at 2 mg per week. Most research protocols run eight to twelve weeks, so two or three vials are usually needed for a full cycle. Once reconstituted, the vial should be refrigerated at 2 to 8 degrees Celsius and protected from light.
How many units is 1mg of CJC-1295 with DAC?
The number of units depends on how much bacteriostatic water you add. If you add 2.5 mL to a 5 mg vial, the concentration is 2 mg/mL, so 1 mg equals 0.5 mL, or 50 units on a U-100 insulin syringe. With 2 mL of water, the concentration is 2.5 mg/mL and 1 mg equals 0.4 mL, or 40 units.
Is CJC-1295 with DAC legal in the United States?
CJC-1295 with DAC is not FDA-approved for human use and is sold only as a research chemical. Selling it for human consumption is not permitted, and it is prohibited by WADA and most athletic organizations. State laws vary, so anyone with questions about legality should speak with a healthcare professional or attorney.
