Ok, so I havent had a pre-workout supp in months so im aware that in part thats why im feeling things that im feeling with this product, BUT, regardless it still works amazingly for what I need it for because in the end, it's all about the gains ppl...all about the gains😎 im giving it a 10/10 on flavor, 10/10 on how fast it works 6/10 on vascularity 9/10 on focus 9/10 on energy, this thing will give you energy for your workout and leave you wanting to keep working out but once you officially call it a day, it also calls it a day SMOOTHLY. picked this up about 3 days ago and might be the best thing ive ever picked up, I highly reccommend it, peace!✌
