Where has the Greenwich w B12 gone?

I started with Greenwich w B12 additive and have had good success with it (35 lbs down since Feb!). The original telehealth I purchased from, and their sister company (Trava and 10rx) no longer carry it. Gimme doesn’t offer it anymore either.

Does anyone know why? Does anyone know of any current telehealth providers that do? I see some offering it with glycine but I’m really hoping to stick with what’s been working best for me so far. And yes, I’ve tried other pharmacies (BPI with B6) along my journey but my body seems to respond better to this one. Thanks!
