After researching, it sounds like these 3 brands are the most recommended...
Thermolife Tribestan
Nutrex Vitrix
Biotest Tribex
Anyone have a comment as to which is best?
I would be especially interested to hear from anyone who's tried multiple brands!
thanks!
i have tried and liked:-
TRIBOSTEN by thermolife
TRIBESTAN by sopharma
TRIBULUS FUEL EXTREME by twinlab
i have not tried VITRIX by nutrex although it was recommended to me.
all the above contain a concentrated extract of tribulus with not only a high saponin % but specifically high (20%) protodioscin saponin %.
it is specifically protodioscin that has been shown to raise LH levels.
