I know there is not much out there for info on halo, but if halodrol is supposed to be OT-than could you stack it with SD. I stacked SD and PP and really liked it-but i had to cut pp stack short a week and a half due to an enlarged lymph node (hodgkins or Clot-test is tonight). I know SD is toxic but halo not as bad as originally thought. Any info would be appreciated. Depending on what happens with my neck-i might try this in spring or i might stick to pp, sd, & Prostan.
