Hi mate
I would definately recommend adding some carbs! immediately post-workout you have a small window of opportunity to replenish your bodys depleted energy stores and start the recovery process.
There are products designed specifically for this purpose eg, Biotest Surge and Chemical Nutrition Pro-Recover. Surge has an almondy flavour but is quite bitter, as is the Pro-Recover Strawberry flavour - this is due to the nature of the ingredients. The chocolate Pro-Recover however is sweet as .. I could drink that stuff just for the enjoyment of it
As a cheaper alternative, Chemical Nutrition produce a plain carb powder called Pro-Fuel which is a bargain IMO as you can mix a scoop or 2 into your whey and voila - instant post-workout shake.
Also, adding carbs immediately post-workout produces an insulin spike which drives nutrients into muscle tissue - hence this is an ideal time to take your Creatine so dump a scoop of that in as well. You then bypass the need for fancy overpriced Creatine delivery drinks.
