There are tons of things at GNC that would trip off a drug screen and tons of supplements that are pro-steroids. I had a kid once, who was "roiding out" on a supplement from GNC. Thinking nothing of it, I kinda blew it off initially. But he had the bottle, unfortunately, the name escapes me. But the dosing regimen is a cycle on, cycle off dosing. And when you look at the chemical composition and its degradation products, it was metabolized to an anabolic steroid. Over the counter at GNC. Thats the thing. The US makes specific drugs illegal. But it takes awhile for that to occur. So, in the meantime, these companies will make supplements that get around the specific bans and make bank until the new product is shut down. It is amazing. It is entirely possible that Ortiz tested positive for a steroid without actually intending on taking steroids. Even if that is the case, the fact would remain that he was "juiced" during his early Boston run.
