I recently bought Finaflex Stim 8 after being recommended to it. I must say it is the most powerful pre-workout I have ever experienced and believe me I've tried and used quite a few. Now im curious if anyone else has tried it. Reason being because when I take it (1 Scoop) I feel like I just took 80mcg of Clen . My heart rate goes through the roof and I feel exactly how I feel if I took Clen. So Im wondering if anyone else feel this way??
