Its a very simple process really. I in particular like to do the following (I usually have an empty GH vial lying around, but if not, buy a sterile 5ml vial). Grab my slin pin (1ml/100iu type) and pull up 1ml/100iu of BW. Pop the amp of the 5000iu HCG powder, and shoot the water in the amp, it dissolves the wafer immediately. Grab a 1 inch, 22g needle on a syringe (slin pin isn't long enough to reach to the bottom of the amp) and suck up all the solution, then I shoot it into my sterile vial and pop it in the fridge. I usually shoot 500 or 1000iu at a time. If I go with 500iu, I suck up to the 10iu mark on the slin pin (1ml/100iu slin pin) which is equivilant to 500iu since the ratio of BW to HCG is 10iu:500iu (1ml of solution=5000iu of HCG). I tried to make it simple.......
