Sure you can take simple sugars after your training session provided you are already somewhat depleted and are using glucose disposal agents to help with insulin sensitivity and glycogen supercompensation.
Try Alpha Lipoic Acid at about 600mgs, Arginine at 2gms, 1gm of
Taurine and maybe some
Creatine and Magnesium thrown in. Take them with your post workout shake and make sure your carb source is liquid.
You'll be in business.
