I started taking BioTrōpic after I had heard about it from a friend of mine. I am always a little skeptical about products and supplements because, quite honestly, most of them don’t work. After about a week of taking the product, I started noticing a difference in my stamina and endurance especially during my sprint workouts. I am always in peak physical condition going into competition, but now I feel I have even more gas in the tank. I almost feel bad telling people about this as I want to keep the secret of BioTrōpic to myself. The truth is this stuff works. I now have all my athletes and students on it with great results.
