The DEA 'proposed' a ban for DMT, Boldione, & Dienolone. Any feedback from companies, suppliers, etc. had to be returned to the DEA by June 24th. As for when the bill actually goes into effect, it's impossible to say. Could be hours, could be months.
But once it does go into effect - all 3 will be classifed as schedule 3 controlled substances. Hence, be illegal to posess without a prescription, like other steroids and narcotics.
