The serial numbers come out as valid off their website. I"m not worried about authenticity of my product. It’s probably just that batch that went faulty.
I went to get the filter from an old school pharmacy beside my work. They only carried medecine, pharmacetucal equipment (vials, syringes, pins, filters) and natural health products.
I baked the vial the same day. I drew the gear in a syringe with a pin, attached the filter to the syringe then a pin to the filter. The pin surprizing fits on the filter and does not leak even though there’s no screw mechanism. I preloaded my gear in separate syringes so i’d be ready to go.
It’s been 2 injections with no infection !
