How long does it take for HCG to start working? My first time using it today. I used a 27G, 1/2" on my belly until my insulin pins come in. I just pinched some fat and injected there. I was going to just go straight in but I thought it might go IM instead of sub Q. Any suggestions on use? I did 500 iu. Will do another 500 iu Tuesday. Will probably lower to 250 iu 2 x week after.
