What is your cycle the dosage depends upon your history and any gyno,
It works great for me at about .05 every 3rd or 4th day, I recommend Nolvadex and AIFM unless you suspect gyno or have a touch of gyno,
Tren and Deca you need cabaser no matter what else you are on.

Femara is a drug that blocks the process of aromatisation, and so reduces the amount of oestrogen in the body. Drugs that work in this way are known as aromatase inhibitors. Other aromatase inhibitors include Arimidex® (anastrozole) and Aromasin® (exemestane).
Femara is a tablet which is taken once a day, ideally at about the same time each day. It does not matter whether this is in the morning or the evening.
Like I say for me once every 3-4 days is more than enought.
