Go and drink "Brands" chicken essence , regularly ..... as in
once in every 3 days ... regular , no need other stuff !
Waist Tonic essence even better ....
Pollen Brand got one , blend with Du-Zhong , Chong-Chao , Pao-Sheng
into an effective waist tonic ....effective !
Who told me that ? A chinese mainland girl i knew when she boarded
my cab , she asked me how many kids i have , i said one , she asked
why i only got one , i replied : " No powerful enough " , i joking
also , but she seriously recommended me this stuff ....
Saying Sporean has lots of stress and performance
wise , got slightly affected .
well , it's not a magical stuff , but long term wise , u'll find it
terribly effective , u can last longer before ejection , and much
more "muscular" in that area .
It's not only improve that "area" , also other parts of the body ,
but mainly stimulate the "balls" area ! 
U have to believe , when men gets older , penis gets weaker ,
unless u got sufficient input , too many output , without some good
input , do u think the "machine" works well ?
U also have to believe , women , in their late 30's , think it's
proven , lustiest of their time . Very horny ! They will never get
tired of sex . They never gets enough .
