Haven't watched tv for probably 6 years my friend.
I wouldn't say "vada is his evil company" He definitely had an association with them.
Vada's most vocal spokesperson is a guy named Victor conte, who went to jail a few years ago because of scandals Involving PED usage and professional athletes. It's understandable that anyone would be a bit skeptical given their history. They are an organization which have some association with corruption.
GSP definitely has been a fighter who's had a black cloud surrounding his career . Many people including fans, fighters and more have speculated that GSP has been on ped's . Some have speculated he's had a GH gut, which is something that comes with abuse of PED's( Not my words) It makes sense that he would want to clear his name to protect his current and future legacy, VADA is / was obviously a way to do that. Taking a stance against PED usage and being a champion for a cleaner sport Is another way to do that. And it worked for the most part.
If GSP did end up doing USADA or WADA under the salt lake city accredited lab while he was fighting, I wouldn't be saying any of this and I would be absolutely with you.
Because he was so Insistent on using VADA, I will always be skeptical.
