I've used Ursolic Acid up to 1 gram per day (4 grams of 25% extract) and Epharms pump spray. I'd say the results were minimal with both. Pump spray may have been slightly better. Both oral 11-Oxo and transdermal XI-KT worked better, but I'd give a slight edge to oral 11-oxo at 1 gram/day over the transdermal stuff.
I have a feeling that my issue with UA may have been that going transdermal was expensive, and my funds were limited, so I couldn't play with doses as much and longer time frames with that compound may work better.
I would like to try UR spray but haven't yet, due to cost.
I think 7-Keto orally and transdermally is one of the most under rated products out there. It is, IMO, maybe even better than Ursolic Acid, but not as hard hitting as 11-oxo.
