Vesugen: Reference Overview and Reconstitution Notes

Vesugen

What it is

Vesugen is a short synthetic peptide bioregulator, the tripeptide Lys-Glu-Asp (abbreviated KED), associated with the Khavinson family of tissue-peptide bioregulators developed in Russian gerontology research. It belongs to the same "ultrashort peptide" class as Epitalon, Pinealon, and other Khavinson cytogens, and this entry is a neutral reference describing its identity, status, and general handling.

Research context and categorization

Vesugen is generally grouped under the Khavinson bioregulator category and, within that, is described as the vascular-oriented member of the family, so it also overlaps with anti-aging and longevity research framing. In the peptide-bioregulator literature it is commonly discussed in relation to vascular tissue and the endothelium, the cell layer lining blood vessels. The theory advanced by the Khavinson group is that these very short peptides interact with DNA at specific sites and modulate tissue-specific gene expression, and on that basis Vesugen has been investigated in experimental models in the context of endothelial function, vascular tone, and markers associated with vascular aging. These proposed uses are investigational. Much of the supporting work originates from a single research group with limited independent Western replication, so the mechanisms and effects are not confirmed or approved, and Vesugen should be treated as a research compound rather than a therapy with established benefits.

Status

Regulatory status: Research-only. Vesugen is not FDA-approved and has no approved human or veterinary indication. It is supplied as a research chemical, and independent clinical validation outside its originating research group is limited.
Sport status: Not specifically listed by name on the WADA Prohibited List. However, as an injectable substance with no approval from any governmental health authority for human therapeutic use, it falls under the WADA S0 category ("non-approved substances"), so athletes subject to the WADA Code should treat it as prohibited.

Reconstitution notes (general)

Vesugen is typically supplied as a lyophilized (freeze-dried) powder that is reconstituted with bacteriostatic water before laboratory use. The resulting concentration equals the milligrams of peptide in the vial divided by the millilitres of bacteriostatic water added. For example, a 20 mg vial brought up with 3 mL of bacteriostatic water yields roughly 6.7 mg/mL, while the same vial with 2 mL yields 10 mg/mL. A reconstitution calculator is available at our reconstitution and blend calculators.

Dilution and handling notes (compound-specific)

Vesugen ships as a lyophilized powder, so it is reconstituted rather than used as a ready liquid. Vials are commonly sold in the 20 mg size, and typical reconstitution volumes fall between about 2 mL and 3 mL of bacteriostatic water, which puts common working concentrations in roughly the 6.7 mg/mL to 10 mg/mL range depending on how much water is added. Because KED is a very small tripeptide built from charged, hydrophilic side chains (lysine, glutamic acid, and aspartic acid), it is highly water soluble and generally goes into solution readily, and it has limited solubility in non-polar organic solvents, so aqueous diluents are standard. Add the water slowly down the vial wall rather than blasting it onto the powder cake, then let the vial stand and swirl gently; the powder usually clears within a minute or two without heating or vortexing. Letting the sealed vial and the water reach room temperature first helps avoid transient cloudiness from cold diluent. Unlike larger or more hydrophobic peptides, KED does not typically gel, turn stringy, or precipitate when concentrated at these volumes, so cloudiness or visible particles after mixing is a signal that something is off (contamination, degraded material, or an incompatible diluent) rather than normal behavior. Avoid vigorous shaking, which can foam and denature peptide at the air-liquid interface; a gentle swirl is enough. A properly reconstituted solution should look clear and colorless.

Handling and storage

Store the reconstituted vial refrigerated at 2 to 8 degrees Celsius and keep it out of light. Wipe the rubber stopper with an alcohol swab before each puncture, and label the vial with the mix date. Observe the general roughly 4-week refrigerated window for reconstituted material, and discard anything that turns cloudy or discolored or that shows floaters.
