Each 1 mL of the solution typically contains:
Cyanocobalamin: 1000 mcg (the active synthetic form of B12).
Benzyl Alcohol: 1.5% (acts as a preservative for the multi-dose vial).
Sodium Chloride: Added for isotonicity (so the injection matches your body’s fluid balance).
Buffers: Sodium Acetate and Glacial Acetic Acid to maintain pH.
Water for Injection: The base liquid.
Pernicious Anemia: For patients who cannot absorb B12 through their digestive tract.
Malabsorption Issues: Often used by those with Crohn’s disease, Celiac disease, or those who have had gastric bypass surgery.
Dietary Deficiency: Supplemental support for strict vegans or individuals with severe malnutrition.
Temperature: Store at room temperature (15°C–30°C).
Light Sensitivity: B12 is highly light-sensitive. It should always be kept in its original carton or a dark place until use.
Multi-dose Safety: Because it contains a preservative, the 10 mL vial can be used for multiple doses; however, it should generally be discarded 30 days after the first puncture (check the specific label for manufacturer’s instruction).
Based on a 500 mcg (50 Units) weekly subcutaneous dose, here is a structured protocol and a log template you can use.
Dose: 500 mcg (0.5 mL / 50 Units on a U-100 syringe).
Frequency: Once weekly.
Administration: Subcutaneous (SubQ) into fatty tissue (stomach or glute).
Timing: Administer on days when you are not taking MOTS-c or GHK-cu to monitor your energy levels and avoid over-stimulation.
Vial Care: Store in the original box (away from light) at room temperature.
The 28-Day Rule: Once a multi-dose vial is punctured, it is generally recommended to discard it after 28–30 days, even if there is liquid left. This is because the preservative (benzyl alcohol) loses its effectiveness over time.
Light Sensitivity: B12 (Cyanocobalamin) degrades quickly when exposed to light. Always put the vial back in its box immediately after drawing your dose.
Color Check: The solution should be a clear, vibrant dark red. If it looks cloudy, contains particles, or has changed to a brownish hue, discard it.
Note: Do not administer this solution intravenously (IV), as most of the vitamin will be rapidly excreted in the urine before the body can utilize it.
