like most of the guys i've run HCG both ways...personally I prefer running it at the backend of the cycle before PCT. When running on Cycle you've got to keep a close eye on your estrogen levels as they will increase....so things like not as feeling as horney, holding water etc. 1000iu for 10 days before PCT gives the bollocks a good kick start and speeds up recovery.

Inject round the belly no closes than 1 inch to your belly button.....pinch up some skin and inject with an insulin syringe....if you are really low BF don't inject at 90 degrees lower the angle....
