What company if you don’t mine asking. I’ve tried tribulus and liked it. I want to try a good butea.I think it is one of the most interesting herbs out there, but I am also biased since my company sells it :P
My recommendation, avoid the extracts. Get a pure root powder, it has a mild taste so it is easy to consume. There are also premium strains out there that have a higher amount of active ingredients than others.
It's interesting because it seems to be both androgenic as well as anti-estrogenic (although this might be from a SERM like effect). Has influence on cAMP in a similar way as forskolin which has studies backing T boosting effects. The DHT effects are also pretty unique. The type of antioxidants are also nice, epicatechin (same as chocolate) being one of them, this one does not seem to have estrogenic effects same as the other green tea catechins.
