Cortagen

Price and cost-per-mg comparison

Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) classified as a Khavinson-class bioregulator derived from cerebral cortex tissue, investigated for gene expression regulatory effects in neural and cardiac tissue. As a Khavinson-class bioregulator, cortagen is proposed to modulate transcriptional activity in aging target tissue by interacting with gene regulatory elements; microarray analysis of cardiac gene expression following cortagen administration has demonstrated broad effects on transcriptional profiles across multiple functional gene categories, suggesting tissue-regulatory activity beyond its cortical tissue origin. Published research on Khavinson-class peptides has further characterized the systematic gene expression regulatory potential of short bioregulator peptides across tissue types, providing the mechanistic context within which cortagen's transcriptional effects are interpreted. Cortagen has no FDA approval or regulatory approval in any major Western jurisdiction; evidence derives from Khavinson-series preclinical studies with no independent clinical trials published in Western-indexed journals. Cortagen benefits investigated in preclinical research include neuroprotective effects in neural tissue, cardiovascular gene expression modulation, and support for vascular wall integrity in aged animal models. As a brain cortex-derived Khavinson bioregulator, cortagen is proposed to regulate transcription in neural and cardiac tissue through chromatin-level mechanisms, potentially preserving tissue-specific gene expression patterns that decline with aging. Research interest encompasses cortagen's role in neurological aging, post-ischemic brain tissue recovery in preclinical models, and combined bioregulator protocols that pair cortagen with cardiovascular and metabolic peptides for comprehensive longevity applications. Cortagen is a research compound with no regulatory approval in any jurisdiction; evidence is limited to preclinical studies and Russian clinical research literature, with no independent randomized trials published in Western peer-reviewed journals.

Methodology

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.

Educational research tools — not medical advice.

Vendor names, product names and prices are as scraped from each vendor's site on the date shown. A COA count is what the vendor publishes and PeptideBase has on file; PeptideBase does not test products itself. Finnrick grades are a third party's rating, reported as-is. Counts are as of 15 Nov 2026.
