Thymalin Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for Thymalin. All information is for educational purposes only.

Quick Answer

In clinical research in Russia, Thymalin is typically administered at 5-20 mg per dose via intramuscular injection, once daily for 5-10 days. Doses are often adjusted based on individual needs and the severity of immune dysfunction. No human clinical dose-ranging trials have been completed outside of Russia.

Standard Dosage Range

Research dosing range: 5–20 mg per dose (injection)

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Immunodeficiency (secondary, post-infection)

10 mg1× daily
Duration

5–10 days

Administered intramuscularly. Cycle repeated every 3-6 months as needed. Often combined with other immunomodulatory therapies.

Chronic Infections (Herpes, CMV)

10-20 mg1× daily
Duration

7–10 days

Intramuscular injection. Used as adjunctive therapy to antiviral medications. Monitor immune response with blood tests (CD4/CD8 counts).

Post-Surgical Immunosuppression

5-10 mg1× daily
Duration

5 days

Administered intramuscularly starting shortly after surgery. Aims to reduce post-operative infection risk and improve wound healing.

Age-Related Immunosenescence

5 mg1× daily
Duration

10 days

Used in gerontological research to improve immune function in elderly subjects. Often combined with Epithalon. Cycles repeated annually or bi-annually.

Cancer (adjunctive therapy)

10-20 mg1× daily
Duration

7-10 days

Used as an adjunct to chemotherapy or radiation therapy in some Russian protocols. Aims to reduce treatment-related immunosuppression.

Timing & Frequency

Injections are typically administered in the morning. Because Thymalin acts via modulation of gene expression, timing relative to meals is less critical than for other peptides.

Cycle Guidance

Most clinical studies run 5–10 day protocols. Some gerontological studies use annual or bi-annual cycles. While Thymalin is considered relatively safe, prolonged continuous use has not been extensively studied. Cycling rationale is primarily precautionary given limited long-term human safety data outside of Russia.

Reconstitution Reference

Common Vial SizeTypically 10 mg per vial
BAC Water Volume1-2 mL sterile or bacteriostatic water for injection
Concentration & DrawAt 1 mL: 10 mg/mL. At 2 mL: 5 mg/mL
StorageRefrigerate at 2–8°C after reconstitution. Protect from light. Keep lyophilized powder at room temperature or refrigerated.
StabilityReconstituted solution stable up to 24 hours refrigerated. Lyophilized powder stable 24-36 months per manufacturer specifications.

Frequently Asked Questions

What is the standard Thymalin dosage for immune support?
Clinical research typically uses 5-20 mg per dose, administered once daily via intramuscular injection for 5-10 days. The optimal dosage may vary depending on individual factors and the specific clinical context.
Are there any known side effects?
Thymalin is generally considered safe, but some individuals may experience mild injection site reactions (pain, redness, swelling). Allergic reactions are rare but possible. Consult a healthcare professional before use, especially if you have pre-existing medical conditions or are taking medications.
How is Thymalin administered?
Thymalin is administered via intramuscular injection. The lyophilized powder is reconstituted with sterile or bacteriostatic water prior to injection.
