The most bioavailable B12 form, delivered where the gut can't limit it.. Everything below is the arithmetic of this vial — what to mix, what to draw, how often, and for how long.

Pre-mixed as 1mg/mL. IM or SubQ. Retest B12 + homocysteine at 8 weeks.
Every step below uses the numbers you entered above.
Swab the rubber tops of the 10 mg B12 vial and the bacteriostatic water vial with fresh alcohol pads. Let them air dry for a few seconds.
Pull 10 mL of bacteriostatic water into a reconstitution syringe (usually a 3 mL syringe with a 21g needle).
Inject the water against the inside wall of the vial, don't blast it directly onto the powder. This protects the peptide from shear damage.
Gently swirl until the powder is fully dissolved and the liquid is clear. Never shake, foaming denatures the peptide.
On your 100-unit (1 mL) insulin syringe, pull the plunger back until the rubber tip lines up with 10, that's your 1.00 mg dose. Tap out any air bubbles, then inject as directed.
Cap the vial and store at 2–8 °C (36–46 °F). Most reconstituted peptides remain stable for 3–4 weeks refrigerated.
Baseline shift. Energy, sleep, or mood may improve within days depending on the compound and prior deficiency.
Full effect stabilizes. Recheck bloodwork (B12, ferritin, homocysteine) where relevant to confirm response.
Most wellness injectables are run indefinitely at a maintenance cadence, cycled only if labs normalize.
