I think the stuff sucks. Not because it won't work but the carrier is crap. Mix it with some DMSO and then try it. Bet it works then.
There are 2 products from QFS that have a DMSO carrier. I've tested one and there is a thread in the cycles forum. It's DMSO + PGF2a. The other is DMSO + yohimbe (and I think u can optionally add clen).
For a quick cheap test, buy DMSO, buy yohimbe hcl. Both are very cheap. Blend, slather and see if it works!
