Well I thought it sounded good and I bought it for around 39.00 .I went in today I had deads ,pulldowns, BB shrugs and bis .I feel this is the best by far supplement I have ever taken before .It does what it says it will do .The thing I liked the most of this product is that you can do much more work than if you had not useded it .I was stronger with way less fatigue .I think the reason I was stronger was the fatigue issue .Before I would do pulldowns at 120Ibs for 8-12 today I was doing my pulldowns at 145 for 8 strick reps for three sets . havent pulled in a year in a half but I pulled 245 for reps of 8 with ease .I added over 5-10Ibs on all my bi work .Again this product is awsome for fatigue .No sides felt great worth the money ..AC
