Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works

A short peptide bioregulator studied in early research contexts around hepatic/gastrointestinal tissue.

Evidence brief

Livagen is described in the literature as a synthetic tetrapeptide, Lys-Glu-Asp-Ala ("KEDA"), one of the Khavinson-type short peptide bioregulators, studied almost entirely by a single research lineage in human-cell-culture, in-vitro, and animal models.

Published dosing for Livagen

Source-linked reference figures with the population and study context alongside each amount. Study arms are not a starting dose, titration schedule, or personal treatment plan. Label records refer to the named approved medicine, not vendor products.

No curated dosing record is available for Livagen in this index yet. That describes our coverage, not proof that no study exists. See the research and cited studies on this page.

Research use only — this reports what an FDA label or a peer-reviewed study published, tied to its species and study context. It is not medical advice, not a recommendation to use, and no dose here is generated by pepmg. Any dosing decision is for a qualified professional. Animal-study amounts do not establish a human dose.

Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing.
