Supplements are just that-- supplements. For me, cutting supps are a last resort after diet and exercise. Have you cleaned up your diet and taken a good look at your workouts yet?
That said, HC-- like most Muscletech products-- is overpriced, overhyped junk in my opinion. OEP however is one of the few stims I absolutely love. Stacked with Alpha T3, it is a killer cutting stack, and frankly the only stack I've ever taken that has had the same effects as good ol' fashioned ECA.
