What is Cardiogen?

Cardiogen is a short, lab-made peptide originally developed in Russia to support heart tissue. It works at the gene level inside heart muscle cells, helping them survive stress and stay healthy over time. It's used mainly in research and by people focused on long-term heart and cardiovascular health as they age.

Healing

Research targets include tissue repair, wound healing, and recovery from injury.

Longevity

Research targets include cellular aging, senescence, and long-term healthspan.

Is Cardiogen FDA approved?

Cardiogen is not an FDA-approved drug. It is intended for research purposes only and is not approved for human consumption, diagnostic, or therapeutic use.

Research Use Only

Cardiogen has not been evaluated by the FDA for safety or efficacy in humans.

No Clinical Oversight

Not manufactured under FDA-regulated quality or clinical standards.

Unregulated Sourcing

Purity, dosing, and sourcing are not verified through FDA testing or oversight.

How Does Cardiogen Work?

It gets inside heart muscle cells and helps turn on genes for building structural and repair proteins while turning down a self-destruct signal (p53) that stressed cells might otherwise trigger. It also encourages supporting cells to lay down new connective tissue, helping the heart muscle stay resilient.

How to reconstitute Cardiogen

View guide

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

Materials needed

Your Cardiogen 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 Cardiogen 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? Cardiogen typically comes in a 20 mg vial. We recommend 3 mL bacteriostatic water 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 Cardiogen vial

With the bac water in your syringe, insert the needle into the Cardiogen 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 Cardiogen vial in the fridge whenever it's not in use. It will stay good for approximately 30 days.

How to Store Cardiogen

Freeze the dry powder somewhere dry and dark. Once mixed with liquid, refrigerate and use within 2–4 weeks, avoiding repeated freezing and thawing.

Lyophilized Storage

-20°C in dry, dark conditions.

Reconstituted Storage

With bacteriostatic water, 2–8°C for up to 2–4 weeks.

Handling Notes

Avoid repeated freeze-thaw cycles.

What Are the Benefits of Cardiogen?

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

cardiovascular support

Supports repair of heart tissue by helping regulate which genes are switched on inside the cell's nucleus.

May improve how well the heart muscle works and performs overall.

May help counter the natural decline in heart and blood vessel health that comes with aging, by helping regulate the body's biological processes.

antiaging

Helps guide which genes are active to support tissue repair, without changing the underlying DNA sequence itself.

Encourages heart tissue to regenerate at the level of individual cells.

What Are the Side Effects of Cardiogen?

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

Who Should Avoid It

How Long Should a Cardiogen Cycle Last?

This breaks down how long a typical Cardiogen 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.
