Personally I would go with Erase as well...if you're looking to stack some cortisol control w/ dermacrine. I think Dermacrine itself might provide a little bit, and Erase will as well. Also Erase, being a natural AI, will keep estrogen low and prevent any unwanted side effects from any possible aromatization of the DHEA.
I will be running a Dermacrine cycle in about two months and I'm on the fence whether to try the Erase or Formestane-LV with it.
