There is a company called valley vet. They sell it. It's called Agri-vet Fortified B-complex. I'll warn you it burns like a mofo and aches for a few hours at only 1-2cc range! However...it's really cheap...approx 6 bucks for 250ml and free shipping. Check your PM.
I may have to try it out. Thanks thats dirt cheap. Think its ok, even though its made for animals? Also whats a good dose for b-complex. My dad is on HRT and also is prescribed b-complex and b12. His dr. told him to take 1cc of b-complex and 1cc of b-12 per week. Is that all you need?
