You need to be more specific. Are you referring to the pills like "Enzyte"? OR the prescription meds manufactured by the big three like Cialis, Viagra, or Levitra?
Once originally owned by Phiszer, the patent on Viagra expired and it wasn''t long before the other two were introduced by competitors. They all perform primarily the same. They allow greater blood flow to your scrotum that allows you to stay stiff.
I can''t vouch for Cialis or Viagra, but I''ve taken Levitra and I can tell you that it works. It''s NOT FOR EVERYBODY, and you may not need it.
I''m not too proud too say at my age I need it and it works. It''s been about a year now and you''ll never know how my wife appreciates it.
Like I''ve said in other posts about this topic, whatever they''re payin'' the researcher who discovered this particular formula, it''s not enough.
That other crap they advertize, the creams and over the counter pills and lotions are BS. Don''t ever waste your money.
