50mg is standard, and really, it's plenty to get you dry and hard looking, if you run it properly. If you follow the up coming Project Get Shredded, we have a couple guys that are going to use Winstrol. The key is, that you need to get rid of the majority of your fat FIRST, then add the Winny in to help take you that much futher. So the cycle I'd suggest would be longer, 10-12 wks for a new user. It would look like this

1-12

Test E 350-500mg EW

Adex .5mg EOD

7-12

Winstrol 50mg ED

IMO, the oral version is a lot easier to deal with. The oral and injectable are basically going to have the same effect. They are the same drug. The injectable may be slightly less toxic because it misses your liver on the first pass but in the end, it still has to be processed by your liver and still is the same drug. ED inject are a pain to deal with, especially if it's water based and especially if you are new to injections. So my advice would be to stick with the oral and split your dose. 25 mg in the morning and 25 mg about 8 hours later.
