Ralox is the definitive solution for gyno. If ralox doesnt work then surgery is your only option.
You should never use letrozole to treat gyno. It is unhealthy, uncomfortable, unpleasant and necessary. It also, btw, is NOT the most effective method of treatment. This has been clinically documented.
Raloxifene on the other hand has minimal sides and is the most effective method of treatment to the point that if you try ralox and it does not work you can comfortably proceed ahead knowing you have tried the best possible option to rid yourself of gyno before going under the knife.
What is the difference? Well it is simple. The breast tissue requires estrogen to not only form and grow but to survive. Letro treats gyno by systemically reducing estrogen to zero levels. That sounds great except for the fact that it is extremely unhealthy for you. It is also very uncomfortable as your joints will hurt bad. Also you will be lethargic, listless, have no sex drive and suffer from ED issues. Raloxifene on the other hand does not effect systemic levels of estrogen. What it does do however is block e2 from reaching the estrogen receptor in breast tissue. By starving the e receptor in breast tissue the tissue will not only cease growing but apoptosis will occur and the tissue will (best case scenario) die. Thats the ultimate goal.
There is no reason to ever put yourself in the unhealthy situation of undetectable levels of estrogen by using letrozole when you have a solution that is proven in medical studies to be the most effective gyno treatment available. That solution is raloxifene. It is so effective it has been known to reverse even pubertal and pre-pubertal gyno as well as aas induced gyno.
As far as dosing you should dose raloxifene at 120mg/day for week 1. After week 1 drop the dose to 60mg/day. You need to plan on at least 2 months of treatment and likely more but 2 months will let you know if it is working. If you see improvement or the gyno is gone in 2 months-great. If nothing has happened you can stop and feel comfortable knowing you tried the absolute best gyno treatment available and surgery is you only viable option. Gyno studies with raloxifene usually run as long as 6 months but rarely will it take that long if it is going to work. 2-4 months, 6 months being the very very extreme.
Hope this helps some people out.
