hospira bac water 10ml Sterile for Injection, USP (10 mL) for Sale – Westend Medical Supply Sterile Water for Injection contains no bacteriostat antimicrobial agent or added buffer and is intended only for single dose injection after admixture with an appropriate aolute or solution 30ml Bacteriostatic Water (25 Pack)

If the volume of the red methyl-B12 shot is large enough, the next urine specimen will be red or it will be some color of red depending on the concentration of the urine

And, as mentioned above, compounded semaglutide products (with or without B12) are not held to the same standards as FDA-approved drugs

Because B12 is water soluble, your body does not store it, so it needs to be replenished on a consistent basis

Bacteria and mold can proliferate rapidly in unpreserved aqueous solutions, creating products that are unsafe to apply to your skin
