Re:all in one powders HELP!!!!
The best source of carbs depends on when you are going to use the product. Sugars for post workout and complex for during the day. I've only used one all-in1 product and it was Synergy (which I rate very highly). The carb content in it is quite low so it gives you flexability when to use it and you can also add other carbs to it if desired. Personaly I think most all-in-1 are very similar it's about finding one which you enjoy drinking.
Other guys and girls on here will have tried a lot more and be able to give you more feedback.
