I don't have an answer for that yet as I still have 35 or so pumps left of the bps before I crack open the primordial. Hah. But the BPS definitely dries fast, I love it. I hope the primordial isn't that messy, it's a bit of a pain before work as it is to lather up in androgen gloop. But I'll let you know how they compare once the bps runs dry.
