Anavar is pretty mild in the way of side effects. It is one of the safest steroids in the way of effecting your hair line, blood pressure and cholesterol levels. The two biggest issues from anavar usage are:
1. Natural testosterone production suppression
2. Liver toxicity
You can prevent side effect #1 by using a good natural testosterone booster in your cycle lay out. It will keep testicular atrophy to a minimum and sort of replace the need for a testosterone base in the cycle. If you are going to run an oral only cycle, that is the smartest way to do it.
You can prevent side effect #2 by using a good liver aid supplement with your cycle. Look for a product based on NAC, TUDCA and Milk Thistle. I really like the product N2guard from n2bm.com.
