What is Livagen?
Plain language first. The technical label stays, but it never stands alone.Overview
It is marketed for liver support and for how tightly DNA is packed in liver cells. There is very little real human research behind it.
Livagen is a 4-amino-acid 'bioregulator' from the Russian Khavinson family.
What it's used for
Marketed for liver support and how tightly DNA is packed in liver cells. Taken in short courses.
How does Livagen work?
What it does in the body, and where.Livagen is 4 amino acids long, written KEDA.
- 01The claim is liver supportReported to loosen the packing of DNA in liver and immune cells, which would let more genes be read.
- 02No citable human evidenceThe chromatin work was in cell cultures. Liver function has not been measured in a person in anything published in English.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.
- Supporting the liver with age, which is the claim made for itResearch only
- Reported to affect how tightly DNA is packed in liver and immune cells, which is the mechanism claimed for this whole family.Early research

Four things to know about Livagen
How much, and do you cycle it?
The range, and whether you take breaks.Research only, daily, in 10-20 day courses. Daily for 10 to 20 days, then a long break Community practice
The whole family is used in short courses repeated a few times a year. That pattern comes from Russian practice, not from a trial comparing it against anything else.
Nothing publishedNo figure
No half-life has ever been published for any of the Russian bioregulator peptides, in people or in animals. The research behind them, mostly from one group in St Petersburg, measures effects on tissue, gene activity and lifespan. None of it measures how long the peptide stays in the body.
You can compare this against the whole library to see where it sits.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
Choose your mix
Measuring the water1 mL = one full 100-unit syringe.
Livagen starts at $30.00 across 16 vendors, typically $2.50 – $3.65 per mg.
18 listings, last read Oct 11, 2026. Shipping and card fees are not included.
How do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized Livagen keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.
