Zeberx is a scam. i really recommend you go elsewhere for male enhancement! i tested out their product for the first month and hated it! it didnt do anything to my sexual performance. they say they are useful for "Bigger, Firmer, Stronger and with long-lasting energy". I used the pills consistently before sex and throughout the day hoping for some sort of results but nothing happened. i didnt get an erection, didnt get any extra satisfaction. in fact i probably had better erections before i started taking these. i was really hoping these pills would of solved my erection problem but i was shocked when i realized it was a scam! and it is rather over priced seeing as they are making money off of selling sugar pills! do not buy Zenerx! waste of time and money
