I have been going through as many topics and postings on here as possible and have either not found or missed finding it as of yet a paper on the efficacy of using HCG as part of TRT? Can someone direct me to a link to a paper that I could share with my doctor regarding the use of HCG as part of the protocol? He is willing to do the testosterone and AI currently. He has been very open to my suggestions and this I think would help him give prescription for it. Right now I am getting HCG on my own.
