I would caution against using Anti-Androgens if you are using a Nandrolone in your cycle.
Test can be convert to DHT and DHT is harsher on the hairline than Test is, so it makes sense to stop its conversion.
However, Nandrolone itself is harsher on the hairline than DHN (dehydronandrolone, which is what nadrolones change into. So by blocking its conversion you are actually increasing the rate at which your hair falls out while on this cycle.
This is really only an issue with the Nandrolones, not an issue with other gear. So if you are using Deca, or Durabolin during a cycle, save your anti-androgens till post cycle.
