Description
While B12 is essential for metabolism and energy, injections do not speed up metabolism or cause weight loss except in cases of deficiency-caused fatigue or poor health

For general educational awareness, the principles that govern reconstitution of lyophilised injectable medicines in regulated clinical settings include: Preparation must take place in an appropriate environment (ideally a pharmacy aseptic unit or clinical clean area) using sterile equipment
I've often posted saying it drip of B12 might be better ...who knows

*All clients receiving B12 injections are encouraged to have a serum (blood) B12 level checked at least every 6 months to ensure that his/her B12 remains in a healthy range.

They have allowed me to book for my next B12 jab in a couple of weeks and I will have a blood test before the injection

If you work under these rules, customers who try to leave your premises with drinks in hand (for example, carrying a bottle or cup outside the premises) may be breaking state law or at least putting themselves at risk in the event of a traffic stop or police inspection
