While were on the topic, just curious as to weather or not running Dutasteride along with DHT-derived steroids would cause problems?
Does nothing to DHT derived steroids, does not prevent MPB from them either.
5AR blockers like Dutasteride and Finasteride are sort of a one trick pony, they only work on testosterone. It is always a good idea to use a 5ar blocker when including testosterone in a cycle.
