I am sure you already have....but just incase, make sure to read though the hcg threads on this site. I am older also, not 50 but over 40. I run my hcg on cycle with my test. 500 iu per week, split into two shots. 250iu Mon & Thurs. I am still new to this hobby so it could just be in my head...but I feel like I orgasm harder, and heavier running hcg... plus the nuts stay big and round. So for me it’s like , “I might not need it, but it has a positive effect and it’s not that expensive “. So I just run it.
