Thymalin is a natural peptide bioregulator derived from calf thymus gland, developed in the Soviet Union in the 1970s. It contains a mixture of thymic peptides that support immune restoration, anti-aging, and tissue regeneration. Research spanning decades has shown significant geroprotective effects, with studies demonstrating up to 2-fold reduction in mortality rates and 4-fold reduction when combined with Epithalamin.
Top researched benefits
Overview of Thymalin
Thymalin's immunoprotective action stems from short peptides (KE, EW, EDP) that specifically bind to double-stranded DNA and histone proteins to regulate gene expression. It stimulates differentiation and activity of T-lymphocytes, especially CD4+ and CD8+ cells, promotes cytokine regulation, enhances antigen response, and stimulates stem cell differentiation. It also affects gerontogene activity and immune system protein synthesis.
immune support
- Stimulates T-lymphocyte differentiation and activity for comprehensive immune system restoration.
- Accelerates recovery of lymphocyte populations including CD4+, CD3+HLA-DR+, B-cells, and NK-cells.
- 2.0-2.4 fold reduction in acute respiratory disease incidence in elderly patients.
longevity
- Clinical studies showed 2.0-2.1 fold mortality reduction over 6-8 years in treated elderly.
- Normalizes basic body functions and improves cardiovascular, endocrine, immune, and nervous systems.
- When combined with Epithalamin for 6 years, mortality decreased 4.1 times vs control.
therapeutic applications
- Faster reversal of lymphopenia and immune marker recovery in severe COVID-19 patients.
- Tumor growth arrest and regression observed in over half of animals in sarcoma studies.
- Normalizes thymus function during aging process.

Thymalin Cycle
The Thymalin Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.
- Day 1-5
- Initial immune modulation begins
- Day 5-10
- T-cell activation and differentiation enhanced
- Week 2-4
- Improved immune markers on blood tests
- Month 1-3
- Reduced illness frequency
- Week 0-0
- Geroprotective benefits with annual cycles

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
