Avar is a lot more expensive than most aas. I have seen lab reports on loads of sources and avar is commonly faked. It's true many things are faked/underdosed but compare it to the likes of dbol and the difference in fakes is huge. The same can be said about primo, tren hex and even tbol.
I ordered Anavar from several Chinese sources in the past. It was ridiculously cheap - and it worked. And take into consideration that I would immediately recognize, if it were faked. I am extremely sensitive to androgens. During a cycle with Winstrol, I quickly got big red cysts on my face. It was unbearable. In contrast, during a cycle with Anavar (50-60 mg/day) my chronic acne DISAPPEARED. What does it mean? It means that when your natural testosterone is suppressed by this dose of Anavar, the level of androgenic activity within your body is SMALLER than normally! It's a great drug in this reagard.
When I raised the dosage up to 80 mg/day, I got only few small pimples. My liver enzymes have never crossed the uppermost normal limit. But cholesterol was always K.O. That's true. Furthermore, my testosterone was also strongly suppressed. At the end of a 6-week cycle with Anavar, I often had 11 ng/dl something, which is only 3% of the normal level. I don't know why, because the average suppression in men is only 40-60%. Perhaps, I was taking steroids for too long a time and my hormonal system had not enough time to recover. After the cycle, it was unpleasant, because without a very effective PCT, I lost all gains within mere 10 days.
So, from the view of liver toxicity, I think that you don't have to be afraid. But you should take care of cholesterol. It is also highly unlikely that moderate doses of Anavar would cause hairloss.
And as for results - Well, you can't expect any big gains of muscle. Anavar is a DHT-derived steroid, which means that it promotes strength and pure muscle mass, not "water muscles". When compared with Winstrol, Anavar is somewhat weaker (certainly on mg per mg basis), but the ratio between anabolism and sides is incomparable. It takes several cycles to observe some changes (especially at 20% body fat - like in me) and you won't become a giant, but I would definitely prefer this sort of physique before testosterone watermeloons.
