Before anything - you should be using an AI from the first day of the cycle, and not wait for the side effects to occur, because it is so much harder to deal with them once they appear. Prevention is the objective with AI use from the beginning of the cycle. This is the first possible reason for gyno here. Then, you should have cabergoline on hand in case prolactin issues appear from trenbolone, which is quite possible. If you used an AI from the first day of the cycle, you would know if your gyno is estrogen related, or progestin related. Neither winstrol, nor nolva will be of help here, as it seems that you already got real gyno. What you need to do, is run an anti-gyno protocol, and run it to the end and to the letter:

2 2.5mgs/ED -NONE- 20mgs/ED 5caps/ED

5 1.25mgs/ED 40mgs/ED 20mgs/ED 5caps/ED
6 0.5mgs/ED 20mgs/ED 20mgs/ED 5caps/ED
TAPER: This phase is required to wean you off the aromatase inhibitors and prevent an estrogen rebound. If you don’t prevent an estrogen rebound, there is a good chance the gyno can come back.
