For a powder, and assuming you are not taking a Micro Creatine Mono, then I would suggest
Green Magnitude by Controlled Labs.
I like the fact that it is has a chelate and DiCreatine Malate.... Not sure if it will be much more beneficial than mono for you, but it does taste good....appears to have a good absorption rate without sugar(the chelate is
suppose to stay stable at the low PH range in the stomach)...... and is price reasonable.
Either way....take it daily the same time of day...earlier in the day might be better. Keep your water intake above a gallon a day IMO.
