Jebrook has you heading in the right direction. I'm a bit surprised you weren't experiencing this on cycle as well with no AI. But sounds like your Nolva is garbage. The RC gamble, uuughghgh. Just a thought, I wouldn't order your Exemestane from the same spot. Burn me once and mess with my tits and you won't ever get anymore of my money!!
I would get a new SERM as well. Any will serve the purpose if it's not actual gyno yet. If it starts to form a mass then Ralox is your best bet.
Ralox at 120 for a few days, then 60/60/30/30
Exemestane 25mg eod for a week, then 12.5 for a few more.
Not really a perfect formula. Just a matter of quality products and feeling it out. Or with actual bloodwork.
But Ralox and Stane got me back on track after a rough Trest cycle. Took over a month with pharma tabs.
