I don't see any value in running this solo, and would not use it either with or w/o erase..
it is a hardener, androgenic in nature, multiple-step conversion to DHT
better if used in a cycle to offset a harsher compound, like something that causes lowered libido or lethargy
what are you trying to accomplish?
and like bolt says, this would be better in a different forum, but oh well since it's already here.......
