Thymalin Protocol Guide
Thymalin is a bioregulatory polypeptide complex extracted from the thymus gland, developed by Professor Vladimir Khavinson at the Saint Petersburg Institute of Bioregulation and Gerontology. It is researched for its ability to restore T-cell mediated immunity, normalize immunoregulatory cell ratios, and enhance natural killer cell activity. Clinical studies in elderly populations demonstrated improved immune markers and reduced mortality over long-term follow-up. This protocol covers reconstitution, intramuscular dosing at 10mg daily for 10-day cycles, immune response timelines, and stacking with complementary bioregulatory peptides.
Protocol Overview
- Compound
- Thymalin (Thymus Polypeptide Complex)
- Category
- Immune Modulation / Bioregulatory Peptide
- Mechanism
- Restores thymic function; normalizes T-helper/T-suppressor ratios; enhances NK cell activity and phagocytosis
- Origin
- Thymus gland polypeptide extract
- Half-Life
- ~2-4 hours
- Vial Size
- 10mg lyophilized powder
- Route
- Intramuscular or subcutaneous injection
- Frequency
- Once daily
- Cycle Length
- 10 days on, repeat 1-2x per year
Dosing Protocol
| Protocol | Dose | Frequency | Route | Duration |
|---|---|---|---|---|
| Standard Immune | 10 mg | 1x daily | Intramuscular | 10 days |
| Subcutaneous Alt | 10 mg | 1x daily | Subcutaneous | 10 days |
| Maintenance | 10 mg | 1x daily | IM or SubQ | 5 days, 2x/year |
Key principle: Thymalin works through bioregulatory mechanisms that restore immune function over short cycles. Extended use is unnecessary; benefits persist for months after a 10-day cycle.
Reconstitution Instructions
Materials Needed
- Thymalin 10mg lyophilized vial
- Bacteriostatic water or sterile saline (1mL)
- Insulin syringes (29-31ga)
- Alcohol swabs
Reconstitution Steps
- Clean vial stopper with alcohol swab
- Draw 1mL bacteriostatic water
- Inject slowly down the vial wall
- Gently swirl until dissolved
- Concentration: 10mg/mL
- Use entire vial as single dose
Expected Timeline
Side Effects & Monitoring
Common Side Effects
- Injection site soreness (mild, transient)
- Low-grade fever in first 1-2 days (rare, indicates immune activation)
- Mild fatigue during first few days
- Generally very well tolerated
Thymalin has been used clinically in Russia for decades with an extensive safety record in immune-compromised and elderly populations.
Precautions
- Caution in autoimmune conditions (immune stimulation may exacerbate)
- Monitor immune markers before and after cycle
- Not recommended during active organ transplant immunosuppression
- Not recommended during pregnancy or breastfeeding
Stacking Recommendations
Compatible Compounds
- Epithalon: Telomerase activation + immune restoration synergy
- Thymosin Alpha-1: Additional thymic immune modulation
- BPC-157: Tissue repair support during immune restoration
- Pinealon: Neuroprotective bioregulatory complement
- Vilon: Additional Khavinson peptide bioregulator
Popular Stacks
- Longevity Stack: Thymalin 10mg/day + Epithalon 10mg/day x 10 days
- Immune Restoration: Thymalin + Thymosin Alpha-1 1.6mg EOD
- Full Bioregulator: Thymalin + Epithalon + Pinealon cycle
Blood Work Recommendations
| Panel | Markers | Timing |
|---|---|---|
| Immune Panel | CD4/CD8 ratio, NK cell count, total lymphocytes | Baseline, Day 14 (post-cycle) |
| CBC | WBC with differential, platelets | Baseline, Day 14 |
| Inflammatory | CRP, ESR, IL-6 | Baseline, Day 14 |
| Metabolic | CMP, liver function | Baseline |
Immune panel testing before and after the cycle provides the most meaningful data on Thymalin's bioregulatory effects. CD4/CD8 ratio normalization is a key outcome marker.
