Thymosin Alpha-1 vs Alpha-Defensin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymosin Alpha-1
Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.
Full details →Alpha-Defensin
Alpha-defensins are small cationic peptides that are key components of the innate immune system. They have broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses.

| Aspect | Thymosin Alpha-1 | Alpha-Defensin |
|---|---|---|
| Mechanism | Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes. | Insert into microbial membranes to form pores, leading to cell death. Also have immunomodulatory effects including chemotaxis of immune cells and cytokine modulation. |
| Typical Dosage | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. | Research compound - dosing varies by application. Typically studied in laboratory and early clinical research settings rather than for general use. |
| Administration | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. | Various routes studied including topical, local injection, and systemic administration depending on application. |
| Side Effects | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. | Limited human use data. May cause local inflammation. Potential for immune activation effects. |
