So I was looking at the updated formula of Formadrol Exreme and noticed you are now using the same complex as T-911 with the addition of Benzyl Ursolate. I've been unable to find any really good info on this particular compound. Can Eric or any of the reps enlighten me? I assume its stronger then what was the previous formula, however I am interested in the specifics of this molecule.
Edit: 3-beta-3-hydroxy-urs-12-ene-28-oic acid is the compound in question.

The inhibitory potency of 3-beta-3-hydroxy-urs-12-ene-28-oic acid extracted from Ilex paraguariensis, a plant used in South American population for a tea preparation known as maté, and its derivatives to inhibit aromatase activity was assessed and compared to a phytoestrogen apigenin and a steroidal aromatase inhibitor 4-hyroxyandrostenedione (4-OHA). Among all compounds tested only ursolic acid 1 showed an efficient and dose-dependent aromatase inhibition with IC50 value of 32 microM as did apigenin (IC50=10 microM), whereas IC50 value of 4-OHA was 0.8 microM. Our results show that the incorporation of a metallocene moiety into the 3-beta-3-hydroxy-urs-12-ene-28-oic acid derivatives decreases the aromatase inhibition. Moreover, comparison of the structure/inhibitory potency relationship of compounds indicates that the presence of cycle A and the configuration of C3-OH and C17-COOH seems to be more favourable to recognize the active site of aromatase and to block its activity.
