Hey bros... I've happen to try product from HK, its pretty popular there...called menergy. Its certified and fully legal... and cheaper than viagras yet doesnt have the side effects of viagras.
DAMN its GOOD STUFF! Its became larger and more sensitive...wah seh... and erection was really good and hard... and the effect lasts for 60 hours! of coz i dun walk around erect all the time... its only when stimulated like u see zhao geng or being rubbed... I just tried it last night with my girl and had many shots with no difficulties at all.
