A polypeptide complex extracted from calf thymus that restores immune function. Used in Russian medicine for immunodeficiency states and as an adjunct in cancer immunotherapy.
Dose: 5-10 mg | Route: Intramuscular injection
The clinical designation for Thymosin Alpha-1, used internationally as an immune modulator. Approved for hepatitis B/C and used adjunctively in immunocompromised patients.
Dose: 1.6 mg | Route: Subcutaneous injection
A zinc-dependent nonapeptide secreted by thymic epithelial cells that is essential for T-cell differentiation. Levels decline dramatically with thymic involution during aging.
Dose: 1-5 mg | Route: Subcutaneous injection
A multifunctional iron-binding glycoprotein found in milk and mucosal secretions with broad antimicrobial, anti-inflammatory, and immunomodulatory activities.
Dose: 200-600 mg | Route: Oral capsule or powder
A family of antimicrobial peptides produced by epithelial cells that form the first line of defense against pathogens. Act as natural antibiotics and immune activators.
Dose: 50-200 mcg | Route: Topical or subcutaneous
