theres tonnes of shit out there like this stuff man. compare the ingredients to others and pick out the best. do your own studies, thats what im doing. Pills like this wont actually make your penis grow, but it will make it harder and filled with more blood causing it to become enlarged when hard and possibly look bigger flaccid as there may be bettter blood flow. im using a product by abundance health which has worked awesome, my dick never felt all that hard when i fuked. after takin this in the first week its rock hard and my girl loves it. u could check it out at abundancehealth.com, but like i said theres loads of products out there like this.
