Which antiandrogen / testosterone blocker should I take?
The best blockers are the GnRHa medications which can be taken as a nasal spray or an injection but they are expensive if you're funding them yourself.
If your funds are limited and you're trying to reduce the effects of testosterone, finasteride is the simplest and safest option (but maybe not the most effective).
Spironolactone and cyproterone are probably equally effective but require you to have more blood tests. Bicalutamide is no longer recommended because of the risks of liver toxicity.
