just wondering about this HCG i just got. this will be my fouth cycle but first time using HCG. i was planning on running 500iu twice a week the last 4 weeks up to my PCT. so i got this HCG, and it's some powder, 5000iu, in one amp and an amp of what appears to be around 2ml of bacteriostatic water. so should i just open the amps, combine them, put 500 iu doses into slin pins and refrigerate them?(HCG does need refrigerated after mixing right?) is any filtering needed, or do i just swirl the powder in with the liquid and draw? i was just going to put .2 ml(since the concentration would be 2500iu/ml)in 8 slin pins and refrigerate. does this all sound right? if not, please help me out. thanks.
