I was wondering if anyone else had noticed any negative sexual side effects while taking a thermogenic or stimulant. I have had several experiences trying different types of thermogenics and energy boosting deals and don't know exactly why this would be happening.
My hypothesis is that possibly these substances act as vasoconstrictors, I'm not sure if that is correct science or term for that matter and therefore might be reducing blood flow to the penis. I'm not saying that's what it is, but that is the only thing I could think of.
The funny thing is, I do just fine with regular caffeine, and if anything it seems to increase sex drive/performance. Anyone else have similar experiences or insight into what may be going on. ?
