| Aspect | Thymosin Alpha-1 | AHK-Cu |
|---|---|---|
| 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. | The copper-binding tripeptide stimulates collagen synthesis and may promote hair follicle enlargement. Works similarly to GHK-Cu but may have distinct receptor interactions. |
| Typical Dosage | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. | Topical: 0.5-2% concentration in serums for skin or scalp applications. Often combined with other growth factors for hair formulations. |
| Administration | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. | Topical application to skin or scalp. Can be used with microneedling for enhanced penetration. May cause temporary blue-green tint at high concentrations. |
| Side Effects | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. | Generally well-tolerated. May cause skin irritation in sensitive individuals. Temporary discoloration possible. |
