Lactoferrin vs Testagen
A side-by-side research comparison of Lactoferrin and Testagen across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Lactoferrin | Testagen |
|---|---|---|
| Full name | Lactoferrin (Iron-Binding Glycoprotein) | Testagen (Reproductive/Thymic Peptide Bioregulator) |
| Category | Immune Support | Immune Support |
| Status | Dietary supplement (GRAS) | Research compound (peptide bioregulator) |
| Mechanism | Sequesters iron from pathogens (bacteriostatic), directly disrupts bacterial membranes, activates NK cells and macrophages, and modulates inflammatory cytokines. | As a signal peptide, it is proposed to regulate gene expression in reproductive and thymic tissue, supporting normal reproductive endocrine function, thymic activity, and immune balance. |
| Molecular weight | 80000 Da | ~ (short peptide) |
| Half-life | ~4-8 hours (oral absorption of fragments) | Short (peptide) |
| Bioavailability | ~15-25% (oral, as bioactive fragments) | Oral (encapsulated) or subcutaneous |
| Typical dose | 200-600 mg | ~1-2 capsules/day or short injectable courses |
| Frequency | 1-2x daily | Once daily |
| Route | Oral capsule or powder | Oral capsule or subcutaneous |
