Frankly, depends on what you can get. Arimidex is usually your best choice but genuine anastrozole (generic name) is expensive and hard to get. Also, depends on how you respond to stuff. There's no one recipe working for all. Remember, bro, we are talking about hormones. You may well need HCG - this really depends on how you respond to Nolva/Clomid which are less intrusive.
Consider this: your wife/GF would use some hormonal anti-conception. She would not feel good. So she just sees her doc and he would change the drug. It's mostly trial-and-error. If you are using gear for more than 2 years you must know what I'm talking about. Bottom line: whoever will give you exact dosage for a specific drug doesn't know what he's talking about...
