Best preworkout on the market in my opinion. The L-citrulline is NOT Malate, which means its purity is in tact and thus more effective. Boron citrate provides the T boost effect which is icing on the cake. Excellent, excellent product.*

GAT Nitraflex is always my go-to for preworkout. In my opinion it is the best on the market. The Grape flavor is good. The Lemon Tea wasn't my favorite.*

It's not the same anymore. It has changed a lot and for the worse. Nitraflex was once one of the best pre workouts on the market, but I don't know why companies have this need to change for the sake of change.*
