no xplode is a preworkout drink that contains a plethora of different substances, but pre workout drinks are caracterized as having mainly Arganine, caffeine, and creatine among other things. cell mass is a post workout drink that's suppose to aid in recovery and mostly contains creatine and glutamine, and true mass is a weight gainer protein. in my personal expierence there are much better products out there for cheaper.

that's a good place to start with pre workout, and im sure others will chime in as well
Post workout
i stick with the basics
whey,waxy maize, oatmeal, creatine, milk, peanut butter, banana all blended up
protein
there are alot of weight gainers out there, although im not a big fan of them but if i had to mention one..
Real gains
overall you are better off using the above post workout nutrition as your "weight gainer" it ends up being alot cheaper, with alot more servings
as far as buying your supplements, gyms and local retailers are a rip off and the employees have absolutely no idea what they are talking about, all there worried about is there commission (generally), your better off shopping at nutraplanet and roaming this board for unbiased opinions and reviews. any questions at all just ask!
