Yeah he uses L-carnitne whilst dieting , about 3-4 grms prior to cardio or working out , and a thermo , thats about it , he uses BCAAs when dieting after workouts as well as clutamine , if he remebers, in the off season he dosent use much of these products cause he eats alot !!!
Water wise whilst dieting he aims for around 3 liters per day , plus a couple of diet sodeas and the like !!
On the Nos front there are many viarying reports on its results so to answer that I give this answer , you need to try it for your self and due to the nature of the product it should have noticeable changes with in 5 days of use, if you dont notice to much change then stick to products that you will , ie creatine ,ZMA etc, I personaly didnt notice to much change when trying these types of products but I have clients whom absolutly love the stuff !! so you need to try it for your self dude !!
