Pros: Decades of clinical use as Zadaxin for hepatitis B/C, certain cancers, and immunodeficiency Well-tolerated with a favorable long-term safety profile in toxicity studies Well-documented immune-modulating mechanism (T-cell, NK-cell, and cytokine activity) that plausibly supports faster recovery from infection and surgery, with older preclinical data also suggesting a direct role in angiogenesis and wound closure Cons: Not FDA-approved for general wellness or anti-aging use in the United States Requires consistent subcutaneous injections over months to see meaningful immune benefits Side Effects: Generally well-tolerated
