Well, it's a useless dose for what he's trying to acomplish. Shut down is not worth it.
Seems we don't agree on a lot of points...lol. First, estrogen will be at it's highest point when taking exogenous aromatizing AAS (Test) not when it's removed from your system. It will then fall to an all time low, things trying to reach natural homeostasis and all.
As far as anti e's go, there are some very smart dudes on both sides of this argument. For me though, personally I can take up to 2 grams of Test a week and have no estrogen issues. Anti e's are super powerful cancer meds and letro is probably the worst one. They can ruin your joints, lead to injury, turn your dick into a drain for your bladder, hurt your gains and just generally screw up a perfectly good cycle. For me I say if you don't need it, don't take it. Others may disagree (Swifto comes to mind as one of the most knowledgeable) but I've been at this for a while and I know what works for me. I guess that's all I know really...
