Marcos, your first post made it sound like you were saying you had some gossip or some reason to believe that those two guys in particular were juicing. The thing is you never actually said anything other than they look bigger/stronger/more jacked or whatever.
My point is that some guys bodies change really easy when they step up their training, which most guys need to do to make the jump from solid brown belt to top notch black belt. You also have to take into consideration that the changes you have noticed have taken place while the guys are young. Tarsis is 23 I believe. That means he was packing on weight from the time he was 20 until now. I can't speak for anyone else but my body changed drastically during that time. Galvao has been pretty much the same for about 3 years now so he was 22-24 (and remaining about the same since he was about 25) when he was still packing on size, which isn't uncommon at all and especially not for someone improving their training and working harder to reach a higher level in profession sports.
I can't say that those guys don't use anything since I don't live with them and tuck them into bed at night but I have no more reason to accuse them than I do to accuse you, who I also have no reason to believe is juicing. I think it has become too easy to dismiss people's hard work and assume that they are taking short cuts. I would think someone like yourself, who has worked his ass off to get in top shape, wouldn't be so quick to dismiss the hard work other guys have put in. It's disrespectful to people who spend countless hours getting themselves in the best shape possible to try to take themselves to the next level. Maybe it doesn't bother you to have to be questioned about it but that doesn't make it right that people question you. I would fucking smack one of my teammates if their lazy asses tried to dismiss my hard work and assume I took the 'easy' route (not that I work that hard

).
I also think that it's funny that so many people talk about how steroids are rampant in BJJ and submission grappling and how they are terrible for the sport while throwing around accusation towards other people and other teams. When you ask these same people they deny knowing anyone who does it. So they know that steroids are rampant in the sport, they have been training for 5, 10, 15+ years yet they don't know anyone on their team that does it.

Give me a fucking break. How the hell can you know that there are so many people juicing if you have no first hand knowledge of anyone? That is ridiculous. I've had this discussion with several people on here and it always results in the same answers.
I'm all for laying having everyone lay their cards on the table. I do think that the people who are on the anti-steroid crusade though should start by outing the people they train with and know first hand are using. So my question is who on your team uses? It should be pretty easy to answer. So again, I'm not defending any one individual but rather that fact that it has become to easy to accuse people and diminish their hard work and effort. I couldn't give a rats ass if someone else juices or not but I can understand why some people take issue with it. But, I can't understand if people are so against it, enough to start calling out people from other gyms, why not first talk about the guys at your own gym first?
