Watermelon and fruit are far better than green apple, Nitraflex has two new flavours

German American Tech’s Nitraflex is a one of a kind pre-workout concentrate. One of the only ones to boost testosterone as well as pump and focus. The long term use of this only makes it work better and until now was only available in green apple. Due to the success of Nitraflex GAT have given back by adding watermelon and fruit punch to the menu.
