Notes
Thymosin Alpha-1 is the most evidence-backed immune peptide — approved in 35+ countries. Good for pre-travel immune prep, post-illness recovery, or chronic immune support. LL-37 adds antimicrobial coverage. This stack modulates (not just boosts) immunity — important distinction for people with autoimmune tendencies. Consult a physician if you have autoimmune conditions.
