Vesugen Dosage Calculator (KED Tripeptide)

A synthetic tripeptide from the Khavinson “peptide bioregulator” programme. The weakest evidence base of anything on this site.

Not approved

Not approved; never evaluated by the FDA

Vesugen is on no FDA compounding list — not Category 1, 2 or 3. It was never nominated, so no FDA evaluation has ever taken place.

No approved human dose exists for this compound in any country. The figures below are the doses used in named published studies, reproduced for reference only. Doses given to rats or mice do not convert to a human dose. The FDA has stated that labelling a product “research use only” or “not for human consumption” does not change its legal status when the seller's own marketing shows it is intended for people.

How the concentration is calculated

This divides the peptide by the water you add. The powder occupies a little volume of its own, which is negligible on a typical vial but not on one with a heavy bulking agent. When a product label states a concentration, use the label’s number.

Published doses

None. No study has published a dose for Vesugen that can be responsibly reproduced. That is a finding, not an omission — every dose figure you see for it elsewhere online comes from community convention rather than a source.

How good is the evidence?

The weakest evidence on this entire site: roughly 27 indexed publications, essentially all from investigators affiliated with the originating institute, mostly in-vitro endothelial work plus small Russian-language clinical reports that do not meet modern randomised-trial methodology, with no independent replication of any core claim. No dose from a controlled trial meeting modern standards exists, so none is reproduced here.

What a search of the literature actually returns

It is worth stating what the evidentiary gap here consists of, rather than leaving it as a vague warning. The indexed literature runs to roughly 27 publications. Essentially all of them come from investigators affiliated with the originating institute. The bulk is in-vitro endothelial work, supplemented by small Russian-language clinical reports that do not meet modern randomised-trial methodology. No core claim has been independently replicated.

That is a different situation from a compound that has been tested and found wanting, and different again from one that is simply new. It is a body of work that has never been subjected to the step — independent replication — that turns a result into a finding.

Never nominated, so never evaluated

Vesugen appears on no FDA compounding list — not Category 1, not Category 2, not Category 3. The reason is procedural rather than substantive: the lists are populated by nomination, and nobody nominated it. No FDA evaluation of this compound has ever taken place.

Absence from the lists therefore carries no information about safety in either direction. It is frequently presented as though it did, usually by vendors pointing out that the compound has not been restricted. Nothing has been concluded about it at all, which is the least informative regulatory position a substance can be in.
