Livagen
Price and cost-per-mg comparison
Livagen is a synthetic tetrapeptide classified as a Khavinson-class bioregulator targeted at liver and hepatocyte tissue, investigated for cytoprotective and anti-aging effects on hepatocellular gene expression and chromatin organization through proposed regulatory mechanisms analogous to other short Khavinson-class bioregulators. Like other Khavinson bioregulator peptides, livagen is proposed to modulate gene expression in target hepatocyte cells through epigenetic and transcriptional mechanisms, with tissue-specific targeting proposed to support hepatocyte function and liver regenerative capacity under conditions of aging-related cellular stress. Published research on Khavinson-class ultrashort peptides has characterized neuroepigenetic mechanisms of action in aging tissue models and demonstrated peptide regulation of cell differentiation in progenitor populations, providing the class-level mechanistic context for livagen's proposed hepatic regulatory effects. Livagen has no FDA approval or regulatory approval in any major Western jurisdiction; evidence derives entirely from Khavinson-series preclinical and class-level studies with no independent clinical trials published in Western-indexed journals.

When Livagen prices moved
5 days in the last 120 on which a feed run read comparable Livagen prices from 3 or more vendors. Each point is the median $/mg across every comparable listing read that day, sized by how many vendors were read. A log of run days, not a continuous series.

How these prices are computed
The short version. The methodology page has the rest.
Source
Prices are read from each vendor's own store feed or product markup (Vendor feed). Every row says which source it came from and when it was read. Prices parsed from page text are not in this index.
$/mg
Listed price ÷ stated milligrams, converted to USD. Packs are priced on total milligrams. Listings sold per kit, per ml, as capsules or sprays, as blends, or without a stated mass are shown but not ranked.
Population
Active online research vendors only. Clinic, pharmacy and telehealth prices are excluded. Medians and the p25–p75 band are computed over comparable listings, one row per vendor product and size.
Independence. Ranking in this index: 0 paid placements.
PeptideBase accepts no payment for inclusion in this index.
PeptideBase takes no affiliate commission on vendor sales.
Ordering is by price, from scraped data.
