I was hesitant to purchase bc I wasn't sure if this would really work or not but after doing research online, I decided to give it a try. It took about a week for it to fully start working (maybe 2) but I've noticed a definite uptick in my sex drive. I even feel a difference in my day to day energy and mind set - feeling more confident. I just subscribed to the holy grail combo so I'm excited to try that next.
