There are tons of pre-workout supplements out there but are they worth using ? I thought it would make for a good blog to see who's using what and why. Personally, I stopped all pre workout supplements myself and simply down a cup of strong black coffee before the gym. I feel that your body get immune to the supplement, like anything else taken peridically, which leads taking double and triple doses to feel any effect. Do you really want to the take double/triple of the daily recommended doses ? Remember your body has to process this, is it worth the hour of rage ? Let's face it, supplements like Jacked3D, crazed, explode, ect...do get you in that zone, kind of like "Tunnel vision" as another member had expressed, but over time these supplements offer zero benefit or nutritional value. Again, is it worth the hour of rage ? So what's your input on pre-workout supplements ?
