Immune Defense Stack
Dual-pathway immune modulation


Why This Stack Works
Thymosin Alpha-1 modulates T-cell activity and enhances antigen presentation — the adaptive immune response. LL-37 provides broad-spectrum antimicrobial action and activates the innate immune system. Together they reinforce both branches of immunity.
This combination draws from Immune research, targeting immune, T-cell, thymus, adaptive immunity, infection, healing. The compounds in this stack act on distinct receptor systems and biological pathways, making them suitable for combined use without mechanism overlap.
All compounds in this stack are supplied by Phiogen with independent third-party Certificate of Analysis (COA) documentation confirming 99%+ purity. They are sold strictly for laboratory and educational use only and are not FDA-approved for human therapeutic use.
Research Protocol
Thymosin Alpha-1: 1–1.6 mg 2×/week SC. LL-37: 100–200 mcg/day SC. Duration: 4–8 weeks.
