Just got my viron and exemestane

[Canes325]

So, just got my viron in. Plan to run is 1 cap 5 on 2 off. Now I'm about 3 weeks back into working out and dieting. A severed ulna artery has kept me out and diet went to **** so I'm sitting at about 22%-25% BF. Because of the high BF I'm concerned (should I be?) of estrogen conversion. But without getting bloods done I have no clue where my estro is. Thus dosing my exem will be tricky. I'm thinking 6mg e3d. Also what do you guys typically see as the first sign of low estrogen? Joint pain? Low libido?
Thanks!
