Tribestan vs regular brands

 A summary on clinical trials of Tribestan vs regular Tribulus based brands

An astonishing 12,000% stronger.

You can see below how Tribestan® is far superior to cheaper imitated brands and why it is the best selling natural testosterone booster today!

Table 1 Shows products analysed for what we call Saponins which are active ingredients.  You can see that Tribestan has a much more powerful profile with an average 54% caompared to a very low 0.1 to 20%.

Table 2  The official results are shown as quantities in 'Furostanol saponins' . Tribestan by Sopharma shows that in 1 tablet Tribestan has around 113mg of Saponins compared to a very low generic 0.5 to 22mg. This makes Tribestan over 12,000% stronger!
