Spirono is weak - pretty weak. 20mg minoxidil is amazing, you're looking at something better in terms of hair, I must say.
Even 25mg (or even 12.5mg) of bicalutamide would be great at blocking ARs with 100% guarantee of no sides except about 9% chances of gyno. It should also raise test by about 200% and estrogen by about 300%, so probability of getting feminizing sides (other than gyno) reduces.
I wouldn’t recommend 12.5MG/day to anyone unless they are using it in combination with a viable amount of estradiol. Within a woman, that could be a great dose for treating acne but within men it’s a different situation. I believe the minimum dose for treating androgenic alopecia would be 25MG/day...
Bicalutamide does lead to feminisation; that increase in T is blocked, which makes it irrelevant. T is just recognised by the brain, which lessens the potential for sexual side effects, etc. It’s just that the feminisation isn’t significant enough, it’s minor.
Something I have been wondering about is: since I have been taking E months prior to bicalutamide, would my E levels further increase? (Due to bicalutamide increasing E)
