I can't think of the exact number off the top of my head. If I was at home I could look at the bottles and tell you. But 1 bottle of bridge is exactly enough for 4 weeks at the normal dose, I believe it's 90 caps. . As for the n2slin that depends on how you take it. 1 bottle could easily last 4 weeks. With the big 30% off sale going on this weekend you could load up on bridge and n2slin and get enough for several runs cheap.
