You can see below how Tribestan® is far superior to cheaper imitated brands.
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 of 54% compared 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!
