You need a very small dose that prevent damage. Common dose is 250iu SC EOD. Try 100iu twice a week. If that does not work, 50mg twice a week. You will need 5000iu or 3000iu vials, 10,000 will last too long. Must be diluted with BA water, 0.9% benzyl alcohol. Some lower doses might be in kits for female ovulation timing where the water is not BA water and the whole vial is injected at once.
Long term use of hCG and anastrozole involves good mood, libido, energy, fertility, healthier testes etc. Long term without hCG is as you describe and elevated E2 in males is not healthy in many ways.
Anastrozole cannot touch testicular T–>E2 production, but will have some effect on peripheral T–>E2.
Arimidex/anastrozole is typically a drug load of 1mg/week, 1/4mg for some. Aromasin is much higher and typically more costly.
For many here, T alone would be too much E2, lost libido, bad mood or depression, fat gain, probably negative effects on prostate and more cardiovascular problems aka lower quality of life and lower life expectancy. Tiny testes are not good for one’s sexual self image and many women would have a strong opinion.
