Roger-Roger, Its not so much that its bad, it just that it wolnt do much of anything post cycle. Also, say mid way to towards the end of pct, you want your body to be back to normal. Test to estrogen level included. If you take armidex, your estorgen level could become lower that it should be and effet your ability to keep your gains.
Its really not needed durring pct. It shouldnt cause any problems "might though", its just that its not needed. Durring a cycle is when you would want to run armidex.
