Ive developed a real tolerance to the general pre WOs (grenade .50 caliber, USN B4 bomb, Applied Nutrition ABE etc) and am currently taking 4 servings and not getting a lot from it
this is like 800mg caffeine so dont wanna be taking this much
i tried not using any for 2 weeks and also i dont have any other form of caffeine at all but made no diff
i miss the tingly ‘high’ feeling and thinking of getting a high stim one
preferrably without a bad crash
recommendations?
