Hey dude, first hcg is for on cycle not pct. also get some bac water to dilute your powder. Get some insulin syringes 5/8 29ga. to inject with. Mix your bac and powder with a ratio that's easy to remember like 5ml bac to make your 5000ius. Also this makes figuring your doses in the insulin syringe easy. The sub q fat on your belly, love handles pretty much any where you have a thin layer of fat will work for inject sites.
