Nelson mentions a 27g .5 inch needle in his protocol. I've got 2 questions. What are all of the different injection sites using that size needle for HCG. Then the same question for testosterone. I'm 36 and am looking at TRT for the rest of my life so I want to spread the needle pokes around if you know what I mean. Can you guys fill me in on all the sites I can inject using that size syringe first for HCG and then for testosterone?
