Athletic Edge Nutrition, or more commonly known as AEN, have revealed a reformulated version of their pre-workout supplement PreSurge. It may have only been just over a year since we last saw the brand edit their energizing formula, but they are indeed back at again. Basically what AEN have done is upgrade their international edition, which was previously a yohimbineless variant of the original. The brand have now put together what is being called the ‘stronger version’. An amplified international PreSurge featuring a boosted caffeine dose at 350mg, and the added power of AMP Citrate. There are a few other differences between the new international and AEN’s US PreSurge, but it is the two ingredients mentioned that are responsible for the product’s ‘stronger’ nickname. While those located stateside won’t of course be affected by the reformulation, it is good to see the brand modernize their pre-workout even if it just their international edition.
