When you take some oral AAS the structure of this compound introduced to the body has bad effects on the body, including the liver... Milk thistle is useful if you dont want your liver to rot and die

now that we know what it is when should we take it post cycle?
during a cycle?

During a cycle... thats when your liver will most likely be enduring a torture test.

Damage will usually stop after you stop taking the steroid because the steroid isnt inside the body to cause the problem and youll be left with what damage was made caused the cycle, if any.
