I have never done Fina. One side of me wants to try it because so many people swear by it, but my other side thinks why take a risk when so many people talk about the side effects, coughing, tightness, etc. I get great results from other AS's and I know what how my body responds to them. I agree with the original poster that this stuff seems a little too much like mix-it-in-the-bathtub/Jethro's Moonshine to me. Although the quality control policies are much more lax in Mexico and some other foreign countries, they still have some quality procedures to avoid a bad rap. A thousand people complaining of bacterial infection is a bad, bad thing for a pharm or vet company. A fuckin' bozo no-no. The stuff from the larger companies is of safe quality. Making Fina seems like a whole different world.
