Insulin help?

Somone gave me three 10mL bottles of 70/30 humulin insulin. I dont really know how to use this stuff so just want to know when to use it and how much SAFE dosage to use? I am a very active triathlete, could i use it pre race or post for recovery?

Thanks,

yeah this stuff is too dangerous for me.......Any of you guys want it?

lol. is this a source post ;) then again so many people can get slin legally anyway...

im a diabetic guys do not take 70/30

why?
