Predator Protein

I bought some stuff called Predator Protein (made by Southern Pharmacueticals) from Hudson Salvage Center. Each shake has 30g of protein and it tastes great (plus it was real cheap). Just wondering if anyone else has ever taken this and if so is it any good??
Thanks

Is it concentrate or isolate?

It is concentrate....Which is better concentrate or isolate??

Isolate is. It has all the impurities removed such as fat, lactose, etc...
