okay i plan on running 500 iu's of hcg every 3-5 days during my cycle. I have 2 amps of 5000iu's coming with 1 ml of solvent each. I plan on ordering some bacteriostatic water to mix 10 ml with it. that way i can inject an even 1ml each time i do a 500 iu shot. I have a couple questions. First, is there a limited amount of time that the hcg can sit in the fridge after mixing it. and second, is there anywhere i can buy some bacteristostaic water and some empty vials together that anyone knows of. (i didnt think the second question constitutes fishing for sources if so lemme know and i'll edit.)
