I can answer with clinical data.
PhytoTest™ is testosterone, derived naturally from a plant instead of made synthetically (like TRT).
Firstly, it is certainly far safer than TRT with no documented side over the last several years of testing (and no needles).
Secondly, PhytoTest™ will not make your body "dependent" on the outside testosterone like TRT.
Finally, PhytoTest™ has been shown to add 80 nanograms of testostereone daily to your free stores, gently raising to healthy levels of a period of days.
Whereas, TRT will deliver a much higher dose of testosterone at the time of injection. However, keep in mind, only a small portion makes it to your "free stores" the rest of the overdosage is what causes the "hormonal" side effects.
In the end, the same goal is achieved, maximized testosterone - PhytoTest™ just does it in a safer (and less expensive) method.
Remember, GDR Labs™ has also privately tested PhytoTest™ on over 15,000 men with exceptional results (Over 90% reported physical benefit).
In my eyes, the results speak for themselves.
