Worked example: 10 mg vial with 2 mL water Concentration: 10 mg divided by 2 mL = 5 mg/mL For a 2.5 mg dose: 2.5 divided by 5 = 0.50 mL = 50 units For a 5 mg dose: 5 divided by 5 = 1.0 mL = 100 units For a 7.5 mg dose: 7.5 divided by 5 = 1.5 mL = 150 units (requires a larger syringe or two draws) Worked example: 30 mg vial with 3 mL water Concentration: 30 mg divided by 3 mL = 10 mg/mL For a 2.5 mg dose: 2.5 divided by 10 = 0.25 mL = 25 units For a 5 mg dose: 5 divided by 10 = 0.50 mL = 50 units For a 10 mg dose: 10 divided by 10 = 1.0 mL = 100 units For a 15 mg dose: 15 divided by 10 = 1.5 mL = 150 units Notice how the 10 mg/mL concentration makes the math cleanest
Coverage is more likely when: You have a diagnosed deficiency: blood work shows your B12 level is below the standard range
These effects, when present, are typically manageable and resolve with continued use or dose adjustment
However, many people in Arizona unknowingly suffer from B12 deficiencies due to diet, age, or digestive absorption issues
B12 injections are a therapeutic treatment that delivers vitamin B12, an essential nutrient, directly into your body
The ability to support multi-dose use makes bacteriostatic water an efficient and practical choice for ongoing research protocols
