Thymalin is a bovine thymic peptide extract with 40+ years of clinical use in Russia. Short 10-day courses restore T-cell counts and CD4/CD8 ratios. One group's data shows striking mortality reduction, but no independent replication exists yet in the Western literature.

Standard protocol: 5 to 10 mg intramuscular or subcutaneous, once daily for 10 days. Repeat every 6 months if you're over 60, or every 12 months if younger. Reconstitution math for a 10 mg vial: add 1 mL bacteriostatic water. Each 0.1 mL (10 units on a U-100 insulin syringe) then equals 1 mg. For the beginner 5 mg dose, draw 50 units. For the standard 10 mg dose, you'll use the entire vial in one shot at 100 units; that means one vial per day for a 10-day course (10 vials total). The thing most beginners miss: you won't feel anything. Thymalin's benefits are lab-measurable, not subjectively perceptible. Get a CBC with differential and CD4/CD8 ratio before your course and again 4 to 6 weeks after. That's how you confirm it's working. The Russian label specifies intramuscular only. Community widely uses subcutaneous without issue, but no published bioavailability comparison exists for the extract form. If you want to match the clinical evidence exactly, go IM in the gluteal or deltoid.
