What is CJC-1295 with DAC?

CJC-1295 with DAC is a longer-acting version of CJC-1295 that sticks to a protein in your blood, which lets it stay active in the body for about a week instead of just hours. This means it keeps growth hormone levels elevated with far fewer injections, often just once or twice a week. It's used in research and some clinical settings for growth hormone support, body composition, and anti-aging goals.

How Does CJC-1295 with DAC Work?

It binds the same pituitary receptor as the natural hormone GHRH, prompting the gland to release growth hormone. A special chemical tag lets it grab onto a protein that's always floating in the blood, turning it into a slow-release depot that can keep growth hormone elevated for over a week per dose.

How to reconstitute CJC-1295 with DAC

View guide

The materials you'll need and step-by-step instructions for safely mixing CJC-1295 with DAC with bacteriostatic water.

Materials needed

Your CJC-1295 with DAC vial (lyophilized)

Alcohol swabs

Bacteriostatic sterile water

3 mL syringes (Luer Lock tip)

25G or 27G needles (Luer Lock). Other gauges may also be acceptable.

Sharps container (optional)

1

Remove the caps

Remove the caps from both your CJC-1295 with DAC vial and your bacteriostatic water vial.
2

Sanitize the rubber stoppers

Wipe down the rubber stoppers on both vials with alcohol swabs and let them dry for about 3 minutes.
3

Attach the needle

Take your 3 mL syringe and needle. Twist the needle's plastic hub into the Luer Lock tip on the syringe to secure it.
4

Draw the bac water

Pull back on the plunger to draw your desired volume of bacteriostatic water. If you overfill, just push the excess back in until you reach the right marker on the syringe.

How much bac water? CJC-1295 with DAC typically comes in a 2 mg vial. We recommend 2 mL of bacteriostatic water, though anywhere between 1 mL and 3 mL is acceptable. For larger vials you can use up to 5 mL — more bac water makes microdosing easier, but insulin needles usually max out at 1 mL per injection. That means a lot of bac water might force you into multiple injections to hit your target dose. Unless you're microdosing, 2 mL per vial is a solid rule of thumb.
5

Insert the needle into the CJC-1295 with DAC vial

With the bac water in your syringe, insert the needle into the CJC-1295 with DAC vial at a slight angle to avoid pressure buildup.

Use a thin needle: Stick to 25G or higher to avoid damaging the rubber stopper. Higher gauge means a thinner needle.
6

Release the water gently

Let the water run gently down the side of the vial. Don't inject it forcefully.

Heads up: Sometimes the plunger pushes itself in as soon as the needle enters the vial. Hold the plunger back so you have full control over how fast the bac water enters.
7

Swirl to dissolve

Avoid shaking. Gently swirl, flip, and roll the vial to dissolve the powder.

Be patient: This usually takes 2 to 5 minutes of consistent swirling, mixing in a circular motion, and gently flipping the vial up and down. The water needs to run through the powder many times to fully dissolve it. Don't shake or get aggressive with it.
8

Check for full dissolution

The solution should be clear with no visible particles. If it's cloudy or clumpy, wait a minute and repeat the swirling step.
9

Cap, dispose, and store

Once you're done, cap the needle and dispose of it (ideally in a sharps container). Store the reconstituted CJC-1295 with DAC vial in the fridge whenever it's not in use. It will stay good for approximately 30 days.

How to Store CJC-1295 with DAC

Freeze the dry powder for up to two years. Once mixed with liquid, refrigerate and use within about a month; don't freeze it again once mixed.

Lyophilized Storage

-20°C, stable up to 24 months.

Reconstituted Storage

2–8°C, use within 28 days.

Handling Notes

Do not freeze after reconstitution.

What Are the Benefits of CJC-1295 with DAC?

What research says it may help with, and how it works in the body.

growth hormone

Provides a steady release of growth hormone that lasts six to eight days from a single injection.

Raises levels of the hormone IGF-1 substantially, and keeps them elevated for an extended period.

Only needs to be taken about once a week, making it simple to use.

body composition

Keeping growth hormone levels raised continuously helps the body break down and use stored fat for energy.

Creates ongoing conditions in the body that favor building muscle, supporting the process of making new muscle protein.

antiaging

Speeds up healing and recovery after exercise or injury.

What Are the Side Effects of CJC-1295 with DAC?

Who should avoid it, warning signs to watch for, and what to know before combining it with other compounds.

Who Should Avoid It

Diabetes history

Cancer history

Predisposed sleep apnea

Stop Right Away If You Notice

Severe joint pain or carpal tunnel syndrome

Excessive water retention affecting daily life

Numbness or tingling in extremities

Significant blood glucose dysregulation

Signs of acromegaly (jaw growth, hand/feet enlargement)

Persistent lethargy indicating adrenal effects

Milder Signs to Watch For

How Long Should a CJC-1295 with DAC Cycle Last?

This breaks down how long a typical CJC-1295 with DAC cycle runs and what research suggests happens at each stage. Research shows that staying on a peptide continuously, without a break, may make it less effective over time.

That's why most research protocols build in a break between cycles, often called a washout period, to let the body reset before starting again.

Week 0-0
Possible water retention, improved sleep, increased appetite
Week 2-3
Noticeable recovery improvements, some report joint discomfort
Week 4-6
Visible body composition changes, increased vascularity
Week 6-8
Continued improvements but watch for desensitization signs
Week 0-0
Most gains maintained; IGF-1 returns to baseline in 2-3 weeks
