Is your buddy a competitive athlete? Otherwise, who the hell tests their T/E ratio.
Unless you're talking about testosterone/estrogen and not testosterone/epitestosterone.
But if that's the case, an 8/1 ratio means nothing; a completely natural person with 500ng/dl serum testosterone could pop some letrozole and have a >20:1 ratio easily.
Yeah he competes, so it was a testosterone/epitestosterone ratio. I should have specified that his "protocol" meant when he was going to cease dosing each compound. He cut the prop out 3 weeks before the test, which should have given him ample time to pass. Dumb decision on his part not finding a more reliable source, but he did purchase stuff from PEP when they were still in decently good standing. And I'm not sure how dosing letro would alter T/E ratios so drastically – unless, of course, you're referring to a test/estro ratio.
