I'm confused, is there different formulas/versions of this?

Currently I've found the following,

Nutraplanet -
Creatine Matrix
(Creatine Monohydrate, Creatine AAB, DiCreatineMalate, Creatine Nitrate, Con-Cret® Creatine HCl (100% Concentrated Creatine), Cinnulin PF®.)

BB -

Creatine Monohydrate, Creatine
CreNitrate™, Creatine AAB,
DiCreatineMalate, Creatine MagnaPower®,
Cinnulin PF®

Supp shop in AUS my brother bought from -

Creatine Matrix 5000mg
-Creatine Mono, Creatine AAB, DiCreatineMalate, Creatine Nitrate, Con-Cret Creatine HCI, Cinnulin PF

And another version off EBAY, which doesn't not contain CreNitrate but all others.


WTF?
