u should get a mass gainer, whey wun bulk u up much and even if
it do, it will take a long time.
flaxseed is mostly to prevent cancer, doesn't really help much for
training.
i suggest u take "Up Your Mass", been said to be not bad. If keen
PM me and i give u the contact, u just go SMS him to ask and
stuff.
If u die die want to take whey, i suggest Optimum Nutrition's 100%
Whey.
