Anyone Used Assault Labs Estro Strike?

[210LBS]

I finally got 2 bottles of this stuff in the mail. I wanted the TD Formestane by Brawn but it seems to be discontinued and I cannot find it anywhere. So, has anyone used this product? I'm looking to run a fairly light cycle like Halo, so I'm thinking I should maybe put it on the side for something more wet. I could always run it as part of PCT but I've read a lot of people don't like to run an AI as part of PCT unpess absolutely necessary because some can be suppressive.

So, any experiences with this? How does it compare to TD Formestane?
