I do not necessarily believe Pac is on steroids. But in this day and age would anyone really be surprise if he was? I honestly have never used steroids though I thought about and researched it. There are so many different forms of steroids that don't bulk you but make you faster, stronger, and/or able to lengthen your endurance. There is so much stuff that beats the system undetectables, masking agents, knowing when to cycle off, etc. I don't box anymore but I am still in the gym often and over time I have come across several amateur athletes who I know for certain have taken a steroid. And too many recreational weightlifters who take steroids. Whether you accept it , see it or not, steroids are rampant. Just look at some of the elite boxers who have either tested positive or have much evidence. Roy Jones Jr.(tested), Shane Mosley(tested), Fernando Vargas(tested), Evander Holyfield(much evidence), James Toney(tested twice). All of these guys except Vargas made very successful weight gains. So it is very easy for people to get speculative of Pac due to his success and how much steroids are really out there. Just so I don't get persecuted by the Pac fanatics, I am a healthy fan of Pac, I want to reiterate that I do not necessarily believe Pac used anything illegal. I actually hope he didn't because Pac is very good for boxing. But no athlete would surprise me if he or she took a steroid. The only thing that would surprise me is if that person tested positive because it is very easy to beat.
