Vilon (20 mg Vial) Dosage Protocol
Quickstart Highlights
Vilon (Lys‑Glu; “KE”) is a short bioregulatory dipeptide investigated for immunoregulatory and tissue‑support effects in experimental models and cell systems.[5][6][7] Preclinical studies commonly use a subcutaneous, pulsed regimen (e.g., very low microgram‑level doses delivered daily for 5 days per 4‑week cycle).[1][2]
- Reconstitute (stock): Add 3.0 mL bacteriostatic water → ~6.67 mg/mL stock (≈6,667 mcg/mL); on U‑100 insulin syringes, 1 unit = 0.01 mL ≈ 66.7 mcg from stock.
- Working solution for micro‑dosing: Prepare a sterile 1 mcg/mL working solution (details below). From this dilution, 1 unit = 0.01 mL ≈ 0.01 mcg (10 ng) for accurate 100‑ng measurements.[12][14][15]
- Typical preclinical cycle: 0.1 mcg (100 ng) subcutaneously once daily on Days 1–5 of each 4‑week cycle.[1][2]
- Storage: Lyophilized peptides are commonly stable at about −20 °C (−4 °F); after reconstitution, maintain cold chain (e.g., 2–8 °C (35.6–46.4 °F)) and avoid repeated freeze–thaw cycles.[13]
Dosing & Reconstitution Guide
Educational protocol aligned with preclinical literature and standard subcutaneous technique
Standard / Pulsed Approach (Stock 3.0 mL = ~6.67 mg/mL; Working = 1 mcg/mL)
Route: Subcutaneous (SC). Frequency: Once daily on Days 1–5 of each 4‑week cycle (preclinical convention).[1][9][10]
| Week / Phase | Per‑Administration Dose | Units (per injection) (mL) |
|---|---|---|
| Week 1 (Cycle 1: Days 1–5) | 0.1 mcg (0.0001 mg) | 10 units (0.10 mL) |
| Week 5 (Cycle 2: Days 29–33) | 0.1 mcg (0.0001 mg) | 10 units (0.10 mL) |
| Week 9 (Cycle 3: Days 57–61) | 0.1 mcg (0.0001 mg) | 10 units (0.10 mL) |
| Week 13 (Cycle 4: Days 85–89) | 0.1 mcg (0.0001 mg) | 10 units (0.10 mL) |
Units above are calculated from a 1 mcg/mL working solution. At the stock concentration (~6,667 mcg/mL), 1 unit ≈ 66.7 mcg and microgram‑level dosing is not directly measurable on standard U‑100 syringes; therefore, prepare a sterile working dilution for accurate micro‑dosing.[12][14][15]
Low‑unit precision note: For ≤10‑unit (≤0.10 mL) administrations, consider 30‑ or 50‑unit insulin syringes for improved readability.[12]
Reconstitution & Working‑Solution Steps
- Reconstitute the vial: Using aseptic technique, draw 3.0 mL bacteriostatic water and add slowly down the vial wall; gently swirl to dissolve. This yields ~6.67 mg/mL stock.[11][14][15]
- Prepare sterile working solution (target 1 mcg/mL): Perform sterile serial dilutions (e.g., first to ~6.67 mcg/mL, then to 1 mcg/mL) in a separate sterile vial to enable 0.1 mcg dosing at 10 units per injection. Label both concentration and date.[12][14][15]
- Storage: Keep lyophilized peptide near −20 °C (−4 °F) and reconstituted/working solutions refrigerated at 2–8 °C (35.6–46.4 °F); avoid repeated freeze–thaw cycles.[13]
- Administration technique (SC): Clean stopper and skin; pinch a skinfold and inject into subcutaneous tissue at 45°–90°. Aspiration is not necessary for SC injections.[9][10][11]
Citation note on schedule: The pulsed five‑day SC schedule at very low microgram doses is drawn from preclinical mouse studies and is presented here for therapeutic educational context, not as clinical guidance.[1][2]

- 16 weeks: 20 syringes
-
Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for stock; additional sterile diluent required for working solutions.

-
Alcohol Swabs: One for vial stopper + one for injection site each injection day.

Protocol Overview
Summary of a microgram‑level, SC pulsed regimen used in preclinical studies.
- Goal: Educational overview of methods used to explore immune modulation and tissue‑support effects of Lys‑Glu in models and cells.[5][6]
- Schedule: 0.1 mcg once daily on Days 1–5 of each 4‑week cycle; repeat for 2–4 cycles as needed for study design.[1][2]
- Dose scale: Microgram‑level per injection (100 ng) in published animal work; human dosing has not been established by high‑quality trials.[1][3]
- Reconstitution: 3.0 mL per 20 mg vial (~6.67 mg/mL stock) plus sterile serial dilutions to a 1 mcg/mL working solution for accurate measurements.[12][14]
- Storage: −20 °C (−4 °F) lyophilized; 2–8 °C (35.6–46.4 °F) after reconstitution; avoid freeze–thaw cycles.[13]
Dosing Protocol
Literature‑based pulsed approach with unit conversions.
- Cycle design: Days 1–5 each 4‑week cycle at 0.1 mcg per day (SC).[1]
- Units from working solution: 1 mcg/mL → 0.01 mcg per unit → 10 units (0.10 mL) per 0.1 mcg dose.
- Technique: 45–90° insertion into subcutaneous tissue; no aspiration; rotate sites.[9][10][11]
- Compounding hygiene: Use sterile technique and clearly labeled concentrations when preparing working dilutions.[14][15]
Storage Instructions
Preserve peptide integrity with conservative handling.

How This Works
Short peptides can regulate gene expression programs relevant to immune and tissue homeostasis; Lys‑Glu (Vilon) specifically has been shown to influence cytokine signaling (e.g., IL‑2) and modulate inflammatory/proliferative pathways in cell models.[5][6][7] In aged mice, chronic subcutaneous Vilon in low microgram doses over months has been reported to improve certain functional measures and survival, though results vary by model and design.[1][3]
Potential Benefits & Side Effects
Observations from preclinical and cell literature.
- Immune‑modulating and tissue‑support signals (e.g., IL‑2 transcription effects; regulation of inflammatory pathways in THP‑1 cells).[6][7]
- In certain rodent models, long‑term SC Vilon has been associated with improved functional metrics and lifespan signals; findings are model‑dependent and not directly generalizable to humans.[1][3]
- Important caution: In a HER‑2/neu transgenic breast cancer model, Vilon exposure was associated with increased mammary tumor development parameters compared with controls, underscoring the need for careful context and risk assessment in oncology‑related settings.[4]
- SC injections may cause mild local reactions (redness, itch, tenderness); rotate sites and use proper technique.[9][11]
Lifestyle Factors
Complementary strategies for consistent protocols.
- Follow a balanced, protein‑forward diet tailored to energy needs.
- Combine resistance and aerobic activity for overall health.
- Prioritize sleep and stress management to support adherence.
Injection Technique
General subcutaneous guidance from recognized clinical resources.[9][10][11]
