Khavinson Bioregulators — Organ-Targeted Short Peptides
The Khavinson bioregulators are the most systematic shelf here: sixteen short peptides, each developed at the St. Petersburg Institute of Bioregulation to act on one specific tissue. They're unusual in the catalog — di-, tri- and tetrapeptides that work at extraordinarily low concentrations by nudging a target organ's own gene expression, rather than flooding a receptor. Once you understand the one underlying idea, choosing among the sixteen is just a matter of naming the tissue.

How the Khavinson system works
Every bioregulator here is a short peptide — two to four amino acids — that acts through organ-directed signaling: it reaches a specific tissue and modulates that tissue's gene expression at sub-nanomolar concentrations. That's a fundamentally different mechanism from the receptor agonists elsewhere in the catalog, and it's why the vials are small and the doses tiny. Each peptide came out of decades of Russian clinical and preclinical work.
Matching a bioregulator to its target organ
The whole shelf is organized by tissue, so you pick by what you want to support:
- Thymogen, Vilon — immune / thymus
- Cardiogen — cardiovascular
- Bronchogen, Chonluten — respiratory
- Prostamax, Testagen — reproductive
- Pancragen — pancreas / metabolic
- Pinealon, Adamax — brain / pineal
- Ovagen — liver
- Vesugen, Vesilute — vascular / urinary
- Cortagen, Crystagen, Livagen — cortex, immune and other regulatory targets
Why the vials look alike
Most of these ship in the same 20 mg vial at a near-uniform price, which throws people off. It's a feature of the class, not a catalog quirk: they're all short peptides made and dosed the same way, so the price reflects the format rather than the target. The difference between two Khavinson vials is which organ they signal, not their strength or scarcity.
Sub-nanomolar dosing
Because they act at such low concentrations, Khavinson protocols use far smaller effective doses than the receptor peptides on other shelves — which is why per-milligram comparisons against something like BPC-157 don't mean much. Reconstitute, store cold, and dose to the protocol for the specific bioregulator rather than by vial-size intuition.
Khavinson peptides — buying & shipping FAQ
What you need to know before ordering khavinson vials.
Which Khavinson bioregulator should I order first?
Pick by the tissue you want to support — the shelf is organized by target organ, not by potency. Thymogen or Vilon for immune, Cardiogen for cardiovascular, Pinealon for brain, and so on. There's no universal 'starter' vial; the right first order is whichever organ matches your goal.
Why are most Khavinson vials the same price?
Because they're the same class of product — short di- to tetrapeptides, made and packaged the same way, mostly in a 20 mg vial. The price reflects the format, not the target tissue. What differs between two bioregulators is which organ they signal, so choose on target rather than on cost.
How are these dosed differently from other peptides?
Khavinson bioregulators act at sub-nanomolar concentrations, so effective doses are far smaller than the receptor agonists on other shelves. That's also why comparing them per-milligram against something like BPC-157 is meaningless — dose to the specific bioregulator's protocol, not by vial-size intuition.
Can I re-freeze a Khavinson vial after reconstitution?
Treat them like the rest of the catalog: reconstituted peptide is stored refrigerated at 2–8 °C and used within its stability window, not re-frozen. The lyophilized powder is what tolerates the freezer. Store cold, keep it out of light, and dose to the protocol for that specific bioregulator.
