Muscles aching after working out

[kitaristi0]

Some good advice here, thanks.

re: Surge, I see a 900g tub of this being sold at £35 (I'm in the UK), and the tub includes 10 servings for £3.50 per serving which is ridiculous. What are some other good, cheaper substitutes? Would something like this be any good?

Also, if you do cardio after weights, do you take the shake after weights or cardio?
