A sucker is born every minute. It’s modern day snake oil and the supplement industry isn’t regulated. I’m sure all the raws come from China, so these guys are most likely popping poor quality, over-priced garbage that has no scientific evidence of working. If it does boost free testosterone by a couple points, it still wouldn’t be enough to notice the effects for someone with low testosterone. I know something that is $10 a month with insurance and it will boost your testosterone big time....testosterone cypionate!
