Winstrol is an AAS and it will not help you burn fat, but it will put on muscle. Winstrol is a popular choice for contest prep because it is known to induce a hard, dry look if you are already somewhat lean. It can be androgenic at high doses and that's why females tend to use tablets as opposed to injections (easier to control dosage) since you can administer the drug orally or intramuscularly.
If you want to lose fat, I would suggest a good ECA stack. If you are looking for something stronger (maybe illegal) you could look into clenbuterol and/or T3 (cytomel). There is also DNP but I do not know very much about it other than it can be very dangerous if not taken properly.
By the way, welcome to AR. I'm pretty sure one of the S-mods will give you female member status shortly. That way you will have access to the female forum (women only, no men
)
It's supposed to be hard! If it was easy, everyone would do it! It's the "hard" that makes it great!
