Well I should have been more prepared for a supplement like this and what it actually does. I took this as suggested and I don't know what happened. I first started to get really warm, and then my entire face and neck turned red, near purple as if I was holding in my breath. I started breathing heavier than normal and my heart rate was jacked! What was strange about it was that the weight I was using didn't feel heavy, I felt the resistance but it didn't feel heavy in my hands as it normally does. Not that I would be able to lift more than i'm capable of but it just didn't have a feel, strange. Needless to say I'm not goin to be taking this again and there is 177 caps in a fresh bottle of 180 if anyone is interested in it for the cost of shipping.
