I was considering buying some veterinary B12 off Amazon. Would you guys feel Ok with shooting the stuff? I see some B complex "mixes", as well as just B12. Both products come in different concentrations (mcg/Ml). How many mcgs should someone be injecting? If you would feel safe using either, which one would you use...complex propriety blend, or just B12?
Here's a list of the ingredients in one of the B complex products:
Fortified, concentrated B Complex injectable contains all six B Vitamins. Contains 100mcg of B12/ml. Each mL of sterile aqueous solution contains: Thiamine Hydrochloride (B1) - 100 mg Riboflavin (B2) (as Riboflavin 5'-Phosphate Sodium) - 5 mg Niacinamide - 100 mg Pyridoxine Hydrochloride (B6) - 10 mg d-Panthenol - 10 mg Cyanocobalamin (B12) - 100 mcg With Citric Acid and Benzyl Alcohol 1.5% v/v (preservative).
