As a matter of principle I wont purchase anything from Denkall, but I have bought the Refovit-B 25mg tabs and loved them. Great value and they work as good or better than any Dbols I have tried before. I will continue to use them, however, I must say I preferred the older pink tabs that contained B-12 over the white tabs (no B-12) out now.
I just finished stacking them with Test/EQ and was very pleased.
