I looked and looked online last nite for a vet supply company that would have 1000mcg/ml b12 to no avail.This site has claimed to have been out of stock for i think 6 months now Nutritional supplements - B Complex Plus - 100 ml. - Injectable solution . Everywhere else online if they are in stock it doesnt state it has 1000mcg/ml or it only has 5mcg/ml.If it states it has 1000mcg whoever has it says out of stock or RX required.Also called local tractor supply,farmers co-op,and feed and seed store and all their injectable b solutions are just 5.0mcg/ml.
Im guessing the 1000mcg isnt available without a RX anymore.
