Tolerability (veterinary): Generally well tolerated in veterinary studies, with occasional mild injection-site reactions
Confusing units with milligrams, using the wrong concentration for your calculations, or drawing 20 units when you meant 2 units, these errors produce either underdosing or overdosing
Adding more BAC water dilutes the concentration
Falling within the reference range is typically a good sign, but it doesn't guarantee your levels are sufficient to support optimal function
Vitamin B12 injections are ideal for men who experience fatigue, poor mood, or nutrient deficiencies
However, because gastric intrinsic factor does not bind the B12 analogs (only B12), the B12 analogs are not reabsorbed but ultimately excreted in the stool (Renz, 1999)
