Hi guys,
It's the first time I post on the forum and English is not my first language. I've been using AAS for about 3 years now.

Let me explain. I am currently on a cycle and having nips sensitivity.
My previous cycle was 2 months before this one and was tren hex 300mg/wk, primo 600mg/wk, test ace 50mg ed. i have done my pct properly and took 2 months off gears.
Right now I'm on test prop 50mg ed and tren ace 70mg ed. At the beginning of my cycle I was using 1,25 mg of letrozole as my anti-estrogen! Maybe 3 weeks into my cycle, my nips became sensible so I made my research and got myself some pramipexole and used 0,5mg every night before bed while increasing letrozole to 2,5mg.
The sensitivity went down to zero so I tought it was all good and I decided to stop my letrozole and start using arimidex instead at 1 mg per day split into 2 doses. I also decreased my pramipexole dosage to 0,25mg.
My nips are starting to get sensible again !!! Last night I got my pramipexole dosage back to 0,5mg and today I added 1,25mg of letrozole.

What did I do wrong ?? I didn't want to use nolva because of the increase affinity of estrogen while using tren...
Is there something I should change in my protocol?

thank you guys in advance.
