Creatine Monohydrate + GAA = The Best Creatine Supplement?

Having heard of a supposedly unique creatine proprietary blend that contains creatine monohydrate + precursor GAA – Guanidinoacetic acid.

The reports from the particular manufacturer/brand says that it has 8,5 times better bioavailability due to four uptake pathways (instead of one for monohydrate only), better for strength (and brain activity) than monohydrate, no edema and GI side effects etc. Appearantly superior to creatine monohydrate on all accounts, if you are to believe the manufacturer. Seems legit looking at the corresponding web site with “studies” and all. That being said, it’s 10 times more expensive than the original product.

Anyone heard of this or even tried it?
