This thread is quite the read. Endosurge Turbo and AlphaMax are the two favorites I've ran, but I have not ran that many products in this category. Also lol at everyone talking about products based off user feedback. User feedback on supplements is fine and dandy, but it has its shortcomings. Just look at the product review pages. You are hard pressed to find many supplements with under a 4.0. You see "perfect" 5/5's all over the place and in multiple categories. With so many perfect fat burners, perfect pre-workouts, perfect test boosters why is everyone constantly running new stuff? User feedback is great, but personal feedback is by far the best. I can't even begin to list the number of supplements that everyone seems to love that I didn't see anything from. You really don't know how good something is for you until you run it, but many people will make their recommendations off the crowd or what they think the product might do for them based on the label.
