Another advantage of injecting stanozolol is that it will negate the first pass of the compound through the liver and therefore is less toxic to the organ. Despite these advantages however, there are a few disadvantages of choosing to inject, namely the comfort of the user. Stanozolol is notorious for causing pain at the injection site upon administration and for possibly several days afterwards, as anecdotally reported by users. This will often cause users to begin administering the compound orally, especially when due to the compound's unique structure, the injectable version can be taken orally as well.
