6'2", 220lbs, BF=15%, 1st cycle in 3 years (1st one done right), 12 weeks, deca/test (420mg/week of each, then PCT, nolva, HCG, armidex; 5000-6000 calories a day, workout/training as follows: each muscle group, once a week, about 15 excersizes per workout (10-12 reps to failure almost every time)

Could someone tell me once and for-all how to take the HCG that I have???
I have it in powder form in a vile. Am I supposed to mix it with water or something else before injecting? Am I supposed to inject it twice a week like some say? Or once a week like others say? Is it 250-500 iu's per inject E3D or is it 4,000 iu's once a week?

Any help would be sooooooo greatly appreciated! Thanks...
