The science
How FORTIFY Blend works, and what the research shows.
How it works
Thymosin alpha-1 is studied for helping T-cells, the immune system's front line, work in balance.
LL-37 is the antimicrobial peptide our own cells make.
BPC-157 is studied for repairing the gut lining and KPV for turning down inflammation.
Clinical evidence
No clinical trial has studied this exact combination.
The evidence is for each peptide on its own, and your physician weighs that when deciding whether the blend fits you.
