I got my scivation xtend grape in on friday. this stuff is . I used it Saturday for my leg workouts which I am usually sore a few hours and the day after. not this time. they also sent some Cold Fusion EX in the package. I felt a small tingle but nothing too much. Keep in mind this is the first creatine supp I have taken. Bumped my squats to 300 x 10 with no burn. Could have been a placebo affect, but I doubt it. Buy some xtend for your recovery drink. The new grape tastes like kool aid.
