Vezugen
Published · Researched 2026-09-21
Overview
Vezugen (also transliterated Vesugen) is a Khavinson bioregulator tripeptide for the vascular system: Lys-Glu-Asp (KED). It belongs to the "cytogen" family of synthesized short peptides developed at the St. Petersburg Institute of Bioregulation and Gerontology, positioned as a geroprotective, vasoprotective peptide that supports vascular endothelial cells and is discussed in Russian biogerontology literature in the context of atherosclerosis, microcirculation, and age-related vascular decline. Sold both as synthesized KED peptide (vials) and as natural peptide-complex capsules/linguals.
Social standing
- Threads/Facebook: No item-specific discussion found in accessible Threads searches or the two accessible Facebook peptide groups. The bioregulator conversation lives primarily in vendor and practitioner channels rather than open biohacker forums.
- Web/community: Vendor ecosystem is the main signal — Core Peptides (US research-vial listing), rupharma.com, peptide-products.com (EU), QI Supplements ("Blood Vessel Bioregulator (Vesugen®)" from $45), TikTok Shop resellers (Khavinson 60-cap listings ~$134.49). The Cerluten research in this same project documented an active Instagram/Threads bioregulator owner community (@peptid_n, @drzaino, @ekaterina_luckylife, @zzengzxc) — category-level evidence that these products have genuine user bases, though Vezugen-specific owner posts were not isolated.
- Recurring praise: the vascular/endothelial positioning is the most "mechanistically legible" of the bioregulators for longevity buyers; capsule format is non-invasive.
- Recurring complaints/failure modes: effects are subtle and slow; vendor quality varies widely; transliteration chaos (Vezugen/Vesugen/KED) confuses buyers.
Social validation
- Tier 3 — weak item-specific validation, moderate category validation. Picked as a genuine Khavinson vascular bioregulator with a defined sequence and a real multi-vendor market, not on item-level community consensus.
- Named sources and what each proves: (1) Core Peptides Vesugen 20 mg listing proves defined-sequence (KED) research-vial availability; (2) rupharma.com ($101/60 caps) and peptide-products.com (€39 lingual) prove the natural-complex capsule/lingual market; (3) QI Supplements bioregulator collection proves US retail normalization of the line; (4) TikTok Shop listings prove current 2026 retail velocity.
- No Facebook Marketplace listings observed.

Pricing
Dated street range (observed 2026-09-21): approximately $45–$101 depending on form. Anchors: QI Supplements "Blood Vessel Bioregulator (Vesugen®)" from $45; peptide-products.com lingual Vesugen €39; rupharma.com Vesugen 60 caps $101; peptide-powder.com wholesale $51–53/box (5-box MOQ, 20 mg × 10 vials); TikTok Shop Khavinson 60-cap listings ~$134.49 (multi-product listings). Facebook Marketplace observed range: none — no listings found.
What's included / what's needed
Capsule/lingual form: bottle of 60 capsules or 10 ml lingual; no accessories needed. Research-vial form: lyophilized vial only — needs bacteriostatic water, syringes, refrigeration. Typical Khavinson capsule framing: 1–2 capsules daily for 1–3 months, repeat in 3–6 months (vendor framing, not a recommendation).
Support reality
Russian/EU resellers (rupharma, peptide-products, e-peptide) offer standard e-commerce support with variable English-language responsiveness; US resellers (QI Supplements, Core Peptides) offer domestic shipping and clearer return terms. No clinical support; authenticity disputes between "original Peptides Co." and white-label resellers are a known community complaint — UNVERIFIED which resellers are authorized.
Regulatory & safety status
Not FDA-approved and not EMA-approved as a drug. Sold as a dietary/food supplement (capsules, linguals) or as a research chemical (vials) depending on vendor and jurisdiction. The underlying Russian clinical literature is real but small, dated, and not conducted to FDA/EMA standards. No approved therapeutic indication anywhere in the US/EU.
Community verdict
Vezugen is the vascular entry in the Khavinson bioregulator shelf: a real defined tripeptide with a plausible endothelial story and a functioning multi-vendor market, but essentially no open-community experience reports in English-language biohacker spaces. Bought on the strength of the bioregulator system as a whole, not on Vezugen-specific evidence.

2 real images on file (img/vezugen-hero.jpg, img/vezugen-box.jpg), both visually verified 2026-09-21: hero shows the genuine QI Supplements "VESUGEN — 60 capsules" box; box view shows the Rebel Peptides "VESUGEN® — 60 capsules" box. Missing views: profile, rear, top, detail, in-use, scale — no genuine traceable photos found; not substituted.
Not medical advice. This is a research summary only; Vezugen is not an approved medicine.
