The difference between 250 and 5000 is having your balls afterward. There's a difference between suppression and shutdown. I'm not trying to argue with you but when I'm under advisement of someone that has 20+ years experience that I can actually look in the eye I tend to believe them. All I wanted was some info about test levels at that dose not a debate on who knows more. I appreciate your feedback it just doesn't make any sense to me.
