i've used qv products and organon's, organon's by far are way better imo....mex gear is cheaper, but for some people, what they put into their system is worth the money and sterility...
If it's made by a company such as Upjohn, steris, ect...and they are made in Canada or the U.S. the quality control standards are the same. EQ and Winny are both vet steroids!!! They are made under the exact standards as Decca, Test ect...
