Tribulus terrestris is known more as an aphrodisiac (for increasing libido and hardness) than for increasing cum loads. There have been some reports of it being effective for the latter, though, which is probably why I first got it years ago, when I first tried various supplements to boost my cum volume. And my experience with the stuff confirmed its reputation: it was indeed a very good aphrodisiac (it helped get me through the first time I experienced the unfortunate “sexual side effects” of Propecia, by ensuring my hardness during sex, though not so much my sensitivity, i.e. ability to cum), but it didn’t seem to do anything for my loads. But still having some on hand, I figured it was worth giving it a go with my more scientific approach.
Which proved worthwhile, because under the influence of tribulus terrestris (specifically Tribestan, though I’ll just be calling it “trib” here) my load volume increased a fair amount, and the volume of the thick white part of my shots increased even more. Plus I got the usual libidinal side effect of better erections – no surprise there.
Unfortunately, there’s some uncertainty in these results. My earlier supplement trials initially had some uncertainty too, due to what I suspected was a reduction of the size of my ejaculations (and libido) as a side effect of Propecia. Taking new baseline measurements confirmed my suspicions, and adjusted the results of my earlier trials accordingly.
I also went off the Propecia as soon as I started noticing those side effects, and that presented a new problem. Eventually my libido would return to normal, along with my cum loads. My new Propecia-side-effects-driven baseline would only be useful for so long. Not only that, but once the Propecia side effects wore off, I wanted to start taking the stuff again. This may seem crazy, since of course the side effects will just come back again, 3 or 4 months after my re-start. But I figure that cycling the Propecia use like this will give me at least some of the benefits of the medication, and none of the bad side effects. And so, I started taking it again 17 days ago.
I suspect that Propecia is itself actually a load booster – for a while, at least. It seems to even boost my libido in the weeks after starting on it. Which is great (for that period, anyway), but this plays havoc with my testing. Is my baseline going up and down on this stuff?
So, I need to take more baseline measurements – a third round of that. If such measurements show my average loads to be larger than before – and I think they will - I’ll have to change my interpretation of the trib trial. For now, then, the results of this trial are tentative.
CONCLUSIONS
Trib increased the volume of my loads by a good amount, but this result is tentative, pending new baseline load measurements. It increased the thick white portion of my cum by a lot. In this trial and in all my previous use of it, trib made my erections come easier and harder, and remain longer. But it has doesn’t cause as much improvement in sensitivity, if any.
