They couldn't really run out of ampoules once they could choose next universe, they just need to stop by in the hangar for few bags hanging there same as Jason 2 did when he sold them to the black guy.

Overall I really liked it, shame they didn't focus more on various alternative universes part, bit went fixated on the wife.

Recently also watched Constellation and Fringe and I think I liked this multiverse TV show the most.

Jason 2 was a bit special though, he was also the only one from that world (he built the box and the hanger, etc). He also had an especially clear view of what he wanted (which in the show meta makes sense).

they were multiple times in hangar (visiting the scared colleague, see the psychologist death etc) so they must be aware there are bags on the wall and once they could choose universe based on small details they could just choose hangar full of ampoules
