There are lots of such letters and reviews collected. You can watch them on our channel https://www.youtube.com/SYNTHESIT/videos
or on the page with all the reviews. This is considered as a miracle, but at the same time - these are real facts.
The key point is that Synthesit works in a complex way, eliminating the cause, not the symptoms. Improving male strength does not appear separately from the whole body, but as part of the overall recovery. This is the most important difference from other means for increasing potency. Some of which do not work amid the overall weakness, and some also undermine the strength of the body.
