I think the Body Research Danabols tested good in a Llewellyn update. They tested at 10mg per tab and of course this is why everyone has great results. However I think the issue is that some people are pawning them off as "human grade" which according to the article is incorrect.
If I purchased Schering test amps and later found out they were knock offs from China I'd be a little upset, even if they did contain 250mg of Test Enanthate each.
