What is Vesugen?
Vesugen is a short vascular peptide bioregulator (a tripeptide, KED) from the Khavinson family, studied for endothelial and vessel-wall support signaling in research models. It is the vascular-tissue member of the short-peptide bioregulator group.
How Vesugen works (research mechanism)
Vesugen research focuses on vascular and endothelial tissue bioregulation - the concept that a tissue-specific short peptide can support normal endothelial function and vessel-wall protein synthesis - within cardiovascular-tissue research models.
Primary research applications
Vascular / endothelial research
Studied for endothelial-function and vessel-support endpoints in models.
Cardiovascular-tissue research
Examined in bioregulator research focused on vascular tissue normalization.
Longevity bioregulator research
Investigated within the broader Khavinson bioregulator framework.
Research dosing reference
Research references commonly cite 2-5 mg daily in short-course bioregulator study cycles. Reference values only - not for human or animal use.
Reconstitution & handling
Vesugen ships as a lyophilized (freeze-dried) powder and must be reconstituted before use in any liquid research model. Allow the vial to reach room temperature, swab the stopper, then add bacteriostatic water slowly down the inside wall of the vial - never spray it directly onto the powder. Swirl gently until dissolved; do not shake, as shaking foams the solution and stresses the peptide. The volume of water you add sets the concentration: a 5 mg vial reconstituted with 2 mL yields 2,500 mcg/mL, so 0.1 mL measures 250 mcg. A correctly reconstituted Vesugen solution is clear; discard if it is cloudy or shows particulate.
Storage & stability
Store un-reconstituted Vesugen vials refrigerated and protected from light for long-term stability; the lyophilized form is robust and tolerates shipping. After reconstitution, refrigerate at 2-8C, keep away from light, and use within the typical research window of roughly two to four weeks. The benzyl alcohol in bacteriostatic water helps inhibit microbial growth across that period. Always label reconstituted vials with the concentration and date.
Common research pairings
Studied alongside other Khavinson bioregulators (Epithalon, Ovagen, Pinealon) in tissue-support research designs.
How Vesugen compares
Vesugen is the vascular/endothelial bioregulator, distinct from the organ bioregulator Ovagen and the neuro bioregulator Pinealon.
Safety & research considerations
Vesugen is a research chemical not approved for human use. For laboratory and in-vitro research only.

Half-life and exposure. Not standardized
Pharmacokinetics (research reference). Human pharmacokinetics are not standardized. Treat exposure as short acting unless compound-specific data or formal formulation labeling indicates otherwise.
Vesugen dose-reference table
| Reference dose | Units (U-100 syringe) |
|---|---|
| 2 mg | 20 units |
| 5 mg | 50 units |
Reconstitution and concentration by vial size
| Vial | Reconstitute with | Concentration |
|---|---|---|
| 20 mg | 2 mL BAC Water | 0.100 mg/unit |
Research timing. Often used in short cycles; consistent daily timing is preferred for interpretation rather than acute-effect timing.
Dose-escalation reference. Begin at the low end of the cycle exposure and assess tolerance before extending duration or combining with additional bioregulators.
Monitoring in research models. Monitor injection tolerance, fatigue, headache, sleep changes, mood shifts, or unexpected organ-specific symptoms. Human standardization is limited.
Reassessment cadence. Bioregulator protocols are commonly structured as short courses. Reassess after 10-30 days and allow an off-interval before repeating unless a clinician-directed objective supports continuation.
Stacking notes (research). Bioregulators can be paired by tissue objective, but introducing one at a time improves interpretability.
Sourcing, purity & Certificate of Analysis
Every lot of Vesugen sold by Peptides Factory Direct is third-party tested to a 99%+ purity target, with identity confirmed by mass spectrometry and purity quantified by HPLC. A Certificate of Analysis (COA) documenting these results is available on request and ties each vial to a tracked lot. Material ships nationwide to all 50 US states with cold-chain handling where appropriate and fast domestic dispatch. This documentation is what separates research-grade Vesugen from unverified material - quality is established before the vial ever reaches your lab.
How to order Vesugen for research
Vesugen can be ordered through the Peptides Factory Direct research portal as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months). Checkout requires confirming you are 21 or older, purchasing for laboratory research only, and that the product is not for human or animal consumption. Bulk and standing-order pricing is available - note it in your order. Open the order portal to view current research sizes and pricing.
