I haven't tried the Novadex myself, but I've had many clients take it and complain about the lack of results. Keep in mind this is still having them on a great eating plan and intense workout sessions. There was some help but not enough to the merit the high price-tag; the cash would be better spent on some quality meals.
Jack3D I've taken and many of my co-workers and clients as well. We all have come to a consensus that it does nothing for actual muscle building, it just cracks you out and gives you a rush of energy/mental high. Surge Workout Fuel actually helps with glycogen potentiation and is a good source of pre and intra-workout carbs and electrolytes. Why throw your money away on an overpriced caffeine source when for a few dollars more you can have one of the best dietary supplements ever made IMO?
Again, this is all supplemental. If your diet isn't right and your not taking your foundational supplements, you better work on getting those down before you worry about test boosters and pre-workouts. Why do you need a test booster at that young age? Your balls fall off or something? Be a man, use your own shit.
