Brotha def need an AI on hand you might not even have to use but good to have. If I’m running any test mg over 250mg a week I need an AI, it’s just simply put the rate at which your body aromatizes. As for dosing if you start getting really oily, breaking out, moonface I’d start with Aromasin.at 12.5mg e3d, and adjust accordingly, maybe EOD, ED…Trial and error, get bloods done
