It really depends on what your looking for in a supplement stack man, I'm guessin your looking for a basic stack with a pre-wo supp and a protein..If thats the case heres a basic stack for you..
Protein- Optimum Nutrition
100% Whey (Everyone Here loves it)
Pure Creatine Mono Powder-I like Pro Labs Creatine Mono
Multi-Vitamin--Doesn't matter too much on the brand
Flax Seed- Optimum also makes this
Casein Protein-Take before you go to bed--Again go with Optimum
For a pre-wo supp you could take something like
no-xplode or
superpump, it really depends on what works for you, different things work for different people
