Hey rino, it's awesome that you used the word "pure" as it shows you are on the right track when looking at supplements.
Our Pre-workout is about as pure as you can get with 97% amino acids in there and a touch of flavouring of course for your convenience. With a 1kg bag being $69, each serve you have works out to be 69 cents!
We do have a $12 flat rate shipping fee but perhaps you could get everything in one? For example, if you take Glucosamine for your joints, some preworkout powder and Whey protein, it definitely becomes worth it.
