Best AIs and anti-estrogens from Steroidify for harsh cycles?

Alright, planning out a somewhat aggressive cycle that's going to involve some aromatizing compounds, so I need to have my AI game on point. Steroidify has a good selection, but I want to hear from those who've run high-dose cycles what their preferred anti-estrogens are from their stock.

I'm looking for reliability and potency. Specifically, I'm trying to decide between Arimidex (Anastrozole) and Aromasin (Exemestane) from their various brands. What have you guys found to be the most effective at controlling estrogen without crashing it too hard?

Any particular brands from Steroidify you swear by for your AI needs? And what about prolactin management with Cabergoline – any recommendations there for quality product from their site? Don't want any gyno or water retention messing up my gains.
