I am about to put my girl on winny. I have a bunch of 50mg vials so I plan on using those, I could get pills but I allready have these so I might as well use them. The question is if should I inject 50mg twice a weed or 1/2 of a vial three or four times a week. If I only inject her with 25mg then I would have 25mg left from that vial. Is it possible to safely store that four a couple of days until her next shot or would I have to throw it away. Thanks for all the feedback. BTW she is 5'8 140pds 23yrs
