actually, i have never heard any insider or person in the know ever make the claim that all pros use the same amounts. if anything, i have heard a hundred times that every pro and every bodybuilder is different and that what works for one wouldnt work for another. each person has their own favorites and does their own thing. some are heavy into growth and insulin and IGF. others are heavy into the basics of test, deca, and dbol. every person is different.
