Anavar costs.....in a nutshell.....A LOT!
10-12 weeks running SPA will probably run close to $300. BTG will be close to the $300 mark also. TT Ox will be a little cheaper. Others, I am not sure about. SPA and BTG seem to be the best - most reliable (you seem to actually get Ox, not something else...).
I've had excellent luck with SPA. In a couple weeks I'll be able to report what I think of TT....
Anavar is expensive, but worth it if you are afraid of sides. MOST people don't get any (or very mild) sides from it.
