I think the reformulated it. There is one call "3 minute Deep" and once called "3 minute DEEEEEEP". The one with the "DEEEEEEEP" is the reformulated one and it SUCKS! But the old one (which is still made and sold) is really good!
I've been looking at this stuff for year's but never tried it.
The "3 Minute Deep" is holy grail status for me.
