Zadaxin
The Book of Peptides is not a clinic and not your doctor. We do not sell, prescribe, recommend, or personalize any compound, and no grade or ranking here is an endorsement. In the United States, most of these compounds are not FDA-approved and are sold for laboratory research only; a few are prescription drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful. Nothing here is a recommendation to buy, possess, or self-administer anything. Consult a licensed physician before any decision involving peptide use.
Approved as Zadaxin in more than 30 countries (not the US) for chronic hepatitis B and C and as an immune adjuvant, with a genuine multi-decade trial history including oncology and investigational COVID-19 research. The strongest independent evidence base of anything in this section.
