Shop Khavinson Bioregulators — 16 Russian Tissue-Specific Peptides

What's on the Khavinson Shelf

Sixteen organ-specific peptide bioregulators developed by Vladimir Khavinson's group in St. Petersburg: Bronchogen, Cardiogen, Cartalax, Chonluten, Cortagen, Crystagen, Livagen, Ovagen, Pancragen, Pinealon, Prostamax, Testagen, Thymogen, Vesilute, Vesugen, and Vilon. Each is a short di- to tetra-peptide (2–4 amino acids) derived from or targeting a specific organ or tissue. Pinealon is available in 10mg and 20mg sizes; most others ship in single-size formats.

How to Choose a Bioregulator

Each bioregulator is named and designed for a specific tissue target:

**Brain / nervous system:** Cortagen, Pinealon

**Heart:** Cardiogen

**Lung / airway:** Bronchogen, Chonluten

**Liver:** Livagen, Ovagen

**Pancreas:** Pancragen

**Cartilage / joints:** Cartalax

**Thymus / immune:** Thymogen, Vilon

**Testes / male hormonal:** Testagen, Prostamax

**Vasculature:** Vesugen

**Bladder:** Vesilute

**Eyes:** Crystagen

Select based on the tissue system relevant to the protocol. Many researchers order Pinealon alongside the Longevity category compounds (Epitalon is also a Khavinson bioregulator but is listed in the Longevity category for discoverability).

Pinealon: 10mg vs 20mg

Pinealon (Glu-Asp-Arg) is the most-ordered Khavinson bioregulator on the shelf and the only one stocked in two sizes. The 20mg vial is the better $/mg. If you're ordering Pinealon for more than a brief protocol, the 20mg is the right choice.

Thymogen and Vilon: The Thymic Pair

Thymogen (Glu-Trp) and Vilon (Lys-Glu) are the two shortest bioregulators — both dipeptides targeting the thymic/immune axis. They are frequently ordered together. Both require BAC water reconstitution and are among the more affordable compounds in this category.

Building an Order

Khavinson bioregulators are compact, moderately priced compounds. Ordering three to four of them typically clears the $200 free shipping threshold. All require bacteriostatic water for reconstitution (one 30mL BAC water vial covers multiple reconstitutions). Store at −20°C; refrigerate after reconstitution and use within 30 days. Same-day dispatch before 2pm EST. Free tracked US shipping over $200. Delivery 3–5 business days.
