Yo dink, I grabbed Liquidex and Aromasin off AG-Guys works like a charm. I noticed about the 2nd week in my nipps started looking a lil puffy but nothing crazy. But I didn't like what I was seeing so I started with the L-dex. At first I dosed it every 3 days but then I found that dosing when you feel like you need to is better since everyone’s body is going to react a little differently. Now, I am not over dosing because obviously estrogen is a key component to muscle building and I don’t want the E levels to fall too low. I haven't even use the Aromasin yet but when I take the L-dex my nips firm up quick and that puffy look goes away. When I look at my chest and everything is looking hard then I know it’s under control. If I let it go for week, especially now since I'm at half a gram a week, I would be getting mad puffy nips. No irritation so far or any burning feeling I sometimes read guys feel just the unpleasant look, but yeah AI's from AG Guys works great for me really impressed with their products so far.
