The best creatine out there as far as absorbtion goes but on the expensive side is
di,tri-creatine orate
di, tri-creatine malate
creatine magnesium chelate

Thhe only people that use all three is Millennium Sport. They make the Ragnarok product. I think it is the best creatine out there and many other goodies in it. Also Man Sport has a product with these creatines in it. I think is is called Scorch. Not sure.
