Thanks bro TS for sharing contact.
Met up with vendor. As a newbie to such products, he was kind enough to give his advise on dosage based on my lifestyle, as well as instructions like no caffeine drinks before popping.
Took half a pill an hour before action. Start to feel body heat up a bit and penis starts to feel a little sensitive. Can really feel erection is much harder and able to sustain as compared to before. A much more enjoyable bonk!
Morning wake up with full throttle erection too. No major side effects for me as first timer.
