Subq without any doubts, I asked doctors (endocrinologists) about that and they all told me that you can use HCG subq, and even now when you buy some in pharmacy (with script of course) it say that you can use Subq in the instruction. Of course that is totally new so maybe if you have some they might not have write that in instruction.
My english is not that good so I hope u understood me. I have a medical study that prove that you can take it subq with the same effect as IM, that study is not in english but in french if you want it I can send it to you.
