Winstrol has to be ran at 30 at least but I'd say 40-50. Anavar probably the same or higher. I'd say pick one and run one at effective dosage, it's cheaper and healthier.
You don't need to run nolvadex and clomid before the cycle as whiskey stated.
As far as dosage, I'd go nolva 40/40/20/20
Stacked with clomid at 50/50/25/25.
If you only pick one just do nolva at that dosage cause clomid isn't as effective. I prefer both tho
