I think it's all bullshit about the shake and bake/ bathtub speed. I mean, it certainly exists, but nobody is trying to ingest that caustic shit except in emergencies. They took it off the market as it was because of exactly the reason you say. Because it worked. Now there is a half-assed garbage product in its place. What if the new formulation is BETTER for the speed? No clue, but wouldn't put it past them for a second.
