First: have you tried other less potentially harmful approaches to helping tinnitus such as l-acetyl carnitine, ala, nac, and a few others? I would try those first. I know what you are feeling as i am a long time tinnitus sufferer.

also VINPOCETINE is suposed to be effective for tinnitus
second; this whole idea that veterinary drugs are somehow contaminated, impure, do not have to hold to strict standards is just so much bullshit. They are controlled just like human drugs by the fda (the FDA Center for Veterinary medicine). This whole "I would never use an vet drug" attitude is so much opinionated elitism. The truth of the matter is that vet b-12 is every bit as potent and safe to use as human grade! Naturally vet drugs may(or may not) come in dosing that might be inappropriate for human use and you need use a reasonable amount of caution to insure that your dose and use are appropriate.
Bottom line, if you do not want to use them for whatever reason, don't ! but do not go around talking them down without just reason.
