guys, I had a Taiwanese gf/ex she opt to take this "after pills" after our intercourse just to be extra safe and yea you can avail this otc in Taiwan, and China and when she visited me here sa pinas, she forgot to bring some from Taiwan and believe it or not we tried to visit all mercury drugs or any pharmacy in ortigas just to avail one but neither of them even know what after pill is, good thing hind naman nabuo lol. anyway suggestion maybe in some Chinese drug stores in Chinatown in manila you can avail some through otc.
PS: this has side effects too similar to birth control pills.
