You can read up on winstrol more here ->

Winstrol is a liver toxic oral steroid, yes, but if you use a good liver aid supplement with your cycle and don't have any pre-existing liver issues, it's not a big deal.
The real problem with winstrol is that it causes joint pain in a lot of users. It's also the single worst steroid for your hair line.
Look into SARMS. I explain what SARMS are in this video here ->

SARMS do not effect your liver, hair line, blood pressure or cholesterol levels.
A very common SARMS cycle is the SARMS triple stack. The triple stack is combination of S4 + ostarine + cardarine.

Cardarine is a great SARM for fat loss and endurance
Ostarine is a great SARM for recovery
S4 is a great SARM for strength gains
You get the best of everything by stacking the three together.
SARMS are only minimally suppressive of natural testosterone production so all that is needed as a mini PCT after a cycle of SARMS is a good natural testosterone booster like HCGenerate ES from n2bm.com.
