When it comes to Anavar, you always want to make sure you're using an approved source. That's why I recommend going with Domestic Supply. Their Anavar is legit.
Domestic Supply is the best source on the planet. Their EQ is terrific. You can run it on a weekly basis and it will give you amazing results. As far as dosing I would run anywhere from 200 to 500 mg a week.
If you want the highest quality tren, make sure you hit up Domestic Supply. Their Beligas and Pharmaqo are on point. That is the best source out there.
