I wouldn't jump to any conclusions about this case without getting a fuller story from both sides.
Anyone with concerns about Silva's first failed drug test should be aware that it came under the darkest period in the Cali AC's darkest period. If there is any one fighter who I'd give consideration to regarding supplements, it would be Bigfoot.
I don't mind trt as long as its needed and the levels stay in range. I'm sure it's a tough balance... And it might not have been on purpose... But high is high... Rules are rules.
