What is Livagen?

Livagen is one of the short peptide bioregulators developed by Vladimir Khavinson’s group in St. Petersburg. Its sequence, Lys-Glu-Asp-Ala, was modeled on peptides isolated from liver tissue, and it is grouped with the hepatic bioregulators in that program.

This listing is Livagen (10 vials × 10mg) from SSRBIO (China), sold on Stairway to Gray with escrow: your payment is held until the order arrives and only then released to the brand.

How it is understood to work

The group has reported that Livagen can decondense heterochromatin in lymphocytes from elderly donors, reactivating genes that are silenced with age. The proposed mechanism is direct peptide-DNA or peptide-histone interaction, which remains a hypothesis outside that research group.

Research status

Research consists of cell-culture work on chromatin structure and animal studies of liver function and aging markers. There are no controlled human trials, and the literature comes almost entirely from one research network.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Request the batch COA · How group testing works

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Specifications

Compound: Livagen
Also known as: KEDA peptide (Lys-Glu-Asp-Ala)
Class: Synthetic tetrapeptide bioregulator
Form: Lyophilized (freeze-dried) powder
Sequence: Glu-Ala-Glu
Per vial: 10mg
Units per kit: 10
Brand: SSRBIO · China

Handling & storage

Supplied as a lyophilized powder; store unopened vials at -20C away from light, and keep any reconstituted solution refrigerated at 2-8C for short-term use.

Concentration check: adding 2 ml of bacteriostatic water to one 10mg vial gives 5 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

Is Livagen the same as a liver extract?

No. Early bioregulators were tissue extracts; Livagen is a defined synthetic tetrapeptide designed to reproduce part of that activity with a known sequence.

What makes Livagen different from Vesugen?

Vesugen is the tripeptide Lys-Glu-Asp linked to vascular tissue; Livagen adds an alanine (Lys-Glu-Asp-Ala) and is associated with the liver. That small change in sequence is the basis for their different tissue associations in the literature.

How much Livagen is in this kit?

10 vials of 10mg each. The lab testing section above shows what the brand’s tested sample actually contained, where a report exists.
