I'm almost on my last week of my cycle and am about to start to work in 500iu's of HCG a day for the final week, then continue for 2 more weeks into the nolv/clomid PCT. My question is for this last week can I mix the HCG and the TestProp in the same needle or do I need to shoot them seperately? I've mixed others before like TrenA and TestP but didn't know if HCG (and it being mixed with water) is different?
