Proviron alone won't be even close to being enough for gyno treatment. You need to run a full anti-gyno protocol, such as this one:
Week Letrozole Nolvadex Cardarine N2Guard
1 1.25mgs/ED 40mgs/ED 20mgs/ED 5caps/ED
2 2.5mgs/ED 60mgs/ED 20mgs/ED 5caps/ED
3 2.5mgs/ED 60mgs/ED 20mgs/ED 5caps/ED
4 2.5mgs/ED 60mgs/ED 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.
7 0.25mgs/ED 10mgs/ED 20mgs/ED 5caps/ED
8 0.25mgs/ED 10mgs/ED 20mgs/ED 5caps/ED
9 -NONE- 10mgs/ED 20mgs/ED 5caps/ED
