First of all, your best bet would be to do a search. There is truly TONS of information.
Secondly, Anavar is IMHO the BEST STEROID in the world. If taken at large enough dosages (35-50mg/day) this steroid will pack on some SOLID muscle, due little or nothing in terms of side effects and you will lose ZERO post-cycle.
The only problem is price. WHile both Winny and Var are expensive, REAL Anavar is truly one of the most expensive compounds in bodybuilding drugs.
Do a solid search and you should quickly figure out which way to go.
