Hey everyone. I have a concern that i would like to have addressed as soon as possible. I used to smoke weed a lot but now i do on occasion (bout 2 times a week or less) and I've also been taking dick pills (from Vaso-Ultra.com) that make your penis bigger. I have been taking the pills for about a week now. But this question came up as i began to research on how it does in fact make your penis bigger. Does smoking weed cause testosterone levels to decrease? I honestly have not found the answer. According to the company that makes these pills they say that the pills release free testosterone and nitric oxide to enter the penis, which then increase it in size over time. But how can it increase in size if the weed is slowing down the testosterone making process. I'm not sure what to do. Please write back to me.
