simple question. i have a bottle of tornel enanthate 200mg-10cc and about a year ago a few ccs were drawn out and then the bottle was stored away until now. i have about 7-8 ccs left id like to use it but i dont know if it is sanitary, the exp date is 3-05 so thats ok. only 2-3 needles were jabbed in there about a year ago and id like to make use of the rest. is this ok?
