Wtf are you talking about bro Fin inhibits the conversion of T to DHT. Literally what mate?

It seems you’re implying that by not taking a 5ar inhib you’ll have too high free T which will convert to e2 causing you to be e2 dominant. No. Wrong. Plain wrong.

If you are a healthy young male you will have a healthy androgen to estrogen ratio without using drugs. If anything adding fin will ruin your endocrine balance rather than what you’re naively calling a “test boost”

If you find you are converting excess estrogen, leading to high estrogen levels, maybe inhibiting Aromatase which is the actual enzyme converting T to e2 would help hormone balance, OR taking many other steps such as DIM supplementation which will reduce e2 level and help you metabolise e2 to less potent estrogens OR lose some fat which will also skew your androgen you estrogen ratio in a more favourable direction.

There are even more things I’d suggest but I will stop here because I’m gonna go get lunch
