Denis, you forgot your shoulders in your training schedule. Also could you be a little bit more specific as far as what your doing in the gym. Instead of just listing the bodypart your training? Provide us with the exercises, reps, sets.

Are there side effects to mixing creatine and whey? I would definatly say no, but also this depends on the type of creatine your using if your using Creatine Monohydrate then you would need something like Dextrose/Maltodextrose to help transport the creatine into the muscles better....If your using CEE you dont need these really. So the answer to this question depends on your creatine.

I recommend taking creatine on workout days and non workout days to keep the body saturated with creatine.

I would take it 30 minutes before your workout so it can get into your body.

Creatine after your workout will help replenish you better, I like to do both before and after so I have an extra kick before I workout and then anther to get my energy back up after

Is your dose good? that also depends on your creatine type. If your taking creatine monohydrate you need a higher dose(10grams), if its CEE the dose if lower (5grams)
