Did you ever experience the dry joints/low libido etc. what we guess is from too low estrogen while experimenting with exemestane (or 11-keto, andeosterone etc)? Just curious
Nope, exemestane is unique among the AI drugs because in the body it gets converted into 6-methylidene-boldenone and has been shown to actually improve bone health. Google "exemestane bone health" and the studies will come up. That chemical is really just a pro-drug for a variation of the steroid boldenone, and it has all of the anabolic and fat-depleting effects of boldenone without the aromatization risk and increases in EPO.
Exemestane makes you slimmer and more muscular
That's probably why it is banned by WADA as a performance enhancing drug.
