I am really amazed at how well this shake works. i have been using it for a while and new it was good but i was always using it with a variety of other things like test, dbol, tren, slin, etc. now i am using the big blast with nothing more than 150mg ew of test. i am losing weight like i plan to. muscle and fat, however i am holding onto more muscle than i expected to and feal so much healthier than i have in years. not having chest pains and fealing like im going to have a heart attack every time i do something is a verry satisfying thing. any way after a w/o i am exousted like you wouldnt belive. it takes everything i have to walk to the truck. my muscles are sore and depleted, but i drink my big blast and my energy, muscle fullness, and overall healthy feeling seems to come right back within minutes. this stuff is amazing. i have no doubt that i would be losing far more muwscle than i am in my new quest if it wasnt for big blast. i have nothing but respect for nelson and protein factory.
