With my cycle I'm taking HCG 300-500iu every 4-5 days. I got 4 little sachets, 2 sodium chloride (1ml) and 2 Pregnyl (5000iu). I'm mainly just seeing if anyone can help me with mixing the two or what I exactly have to do correctly. is it also necessary to use the distilled water or can I get away with not using it? what about keeping the HCG in the fridge? I live with someone and would preferably like to keep this private and not try and hide any of this stuff in the fridge. any advice helps! thanks!
