Pfizer in still the manufacturer for Viagra - Yes most generic's drugs do come from India but Generic only means the drug may differ in Size, Bulk, Texture, Packaging, Shape, Color, Flavour or Binding.
Generic drugs carry the same active ingredients that the brand does.
The active ingredient makes the medication work.
It also must be equivalent in strength, and dosage to the original brand-name product.
Generic medication sometimes have a different pharmaceutical name to - when coming from other countries.
I personally would not recommend buying Medication/Drugs on CL
I know all this information as before I was an SP - I worked in the Pharmaceutical Indusrty .
