Citadel Nutrition: Tier 1

Citadel Nutrition's Tier 1 preworkout manages to be at once both very familiar and yet startlingly original. Familiar because it uses nothing but what are already widely used ingredients. Original because despite the fact they are familiar ingredients, Citadel have gone to the actual studies on each of the ingredients in their product and then produced a product in Tier 1 which uses the exact same dosages shown to impart positive benefits in performance in athletes. Furthermore, Citadel have also ensured that there is nothing of questionable scientific merit within Tier 1 making it the undoubted go to preworkout for those out there who remain sceptical about supplements.

Tier 1 is a supplement which is perfect for anyone to be able to train on, beginner or experienced trainer and dosed correctly you should never need more than a single scoop. It won't produce some of the ultra-intense feelings some preworkouts promise but what it does do is deliver performance, backed by science.
