here is another question for you guys, I think I under dosed my first shot because on my barrels there are 2 measurements, one is marked cc and the other is marked M, in my excitement I forgot that cc and ml are the same thing, and read the M side of the syringe not the cc, and 1 M on the syringe was = to just a little over .5 cc/ml, so I guess my question is should I just correct it next time or take the rest today???
