There are at least 2 European studies and 2 in-house trials that are suggestive of an effect on tribulus and test levels. Unfortunately, the one thing that has not been reported is whether or not that increase is at all significant (in other words, the results have been rather vague and not of the highest quality). Fortunately (or unfortunately for those spending their hard-earned $$$ on it), neither have the studies that purport tribulus to have no effect done a real QUALITY study on the extracts (and none with the dose suggested to have max benefit in the studies - 1500mg, which by default gives more of the protodioscin concentration).
So - then...even if the increase in test is significant, what else need be evaluated?
[1] acute or chronic effects on muscle mass?
[2] how long serum test would remain elevated?
[3] distinct range of increases sought after?
* See, unless an individual reaches pharmacologic (or supraphysiologic) levels of test, the increase after taking the herb (even standardized) may not mean a damn thing. For one, none of the trials in any regard have explored confounding variables...like:
- the serum test rise after an intense power workout/weight session
In the mean time, I go against the grain and suggest that if you are to experience a supraphysiologic response - those familiar with my writing are certain that I recommend AM dosing (rather than the before bed protocols developed by the gurus of the world). In the morning, natural test is highest...IF trib is to have any significant effect, it would be while building on this value in my opinion (especially if the elevations is merely acute).
That is all anyone can say we KNOW.
