HCG - Clomid

HCG - clomid question. I have been on Hormone Replacement Therapy for almost 3 1/2 years. I am 57 years young and have worked out at least 3 times a week for the last 45 years. I have never done steroids before my doctor put me on HRT for anti-aging purposes. My Doctor has me on 1 IU of GH daily (6 on 1 off) and ¾ cc of Depo-Testosterone(200 mg) every seven days. My blood test show IGF levels of 490-520 and my Total Testosterone levels range between 950-1450, free between 35-48. I am 5-8 and weigh 205 with about 11-14% body fat. I feel great, I am getting bigger and stronger, and my cardio fitness has greatly improved. I am having only one problem, and that is the “shrinking NUT syndrom” as they are now the same size as they were when I was 12 years old. My doctors has never put me any type on/off cycle or prescribed HCG or Clomid. I have tried to find some answers in the other post but they mostly address anabolic cycles, not long term therapy. Does anyone have any suggestion on some type of on/off cycle or how much and how often I should take HCG without getting off my Test injections? Your help would be greatly appreciated. THANKS GUYS!
