I did not expect the great results I got from Animal Pak. This is one of the old school supps that has been around for a long time. I noticed while taking it, my energy was higher then normal for sustained periods of time and I also noticed better recovery. Animal Pak floods your system with high doses of vitamins(higher then your average multi) and more important, good doses of minerals like zinc, magnesium, iron which I feel I was deficient in from diet.I also like the fact it has Uni Liver which is dessicated liver, another staple of the classic era bodybuilders. There are also micro nutrients like lutein and lycopene for eye health. Overall, a necessary addition when you are training hard. I want to try the powder version which I would prefer to taking multiple pills..
