Solidrock - the pharma business is very thorough for exactly this reason. People can die when they misunderstand instructions or don't follow directions (this includes trained nurses in hospitals screwing up units or a calculation). This extends straight down to the labels, packaging, and inserts. Give them a read. The essential plain english ingredient is dosage in "mg/ml". Even single dose 1ml vials are labled as such - the units are clear and unobscure. I've read your posts, you are decently educated and not dumb. It's an honest mistake (albeit I've never heard of this happening before and certainly not to this degree). Luckily with roids you can get away with a lot. While I would certainly disregard a lot of the negative comments, you really need to examine how this happened. I get the feeling you wanted to do this stuff so badly that you rushed when you really should have waited. You didn't read the boxes, labels, or package inserts over this entire time until someone pointed out the dosage issue. That strikes me as careless and even a bit odd as the first time people get a bunch of drugs they generally spend a lot of time 'playing' with them and looking everything over. I don't know exactly how this happened and I imagine you'll be okay given nothing has developed yet but I wouldn't simply write it off and move on. Units on meds are important and very very clear for a reason. Somehow this got missed and I think a constructive use of time would be to figure out how exactly that happened to someone who is mature and writes with a fair amount of eloquence so is obviously decently intelligent. I'm not coming down on you but the next time you think you know enough and are excited to do something, the penalty for error may be severe. I would try to understand exactly what behavioral factors played a part in this before casually writing it off as a simple mistake.
