Vitamin B12 Injectable

I have only used .25ml of this Vitamin B12 injectable once a week for the past 2 weeks. I can already see an improvement in my 15 year old cat Keta. She is more social and hangs out with me as before she isolated herself upstairs probably because she didn't feel good.

Vitamin B12 injection

I can't give review yet as I've only given one injection. My vet wants me to give one injection weekly for 6 weeks. Then retest my cat to see how the B12 is working. I can update review after that.

Had to wait too long

Friday- Order Friday- Email from Chewey that I needed a written script Friday -email vet I need written script Tue- Vet has script ready Tue Drive 4 miles to vet Tue- mail script Sat - email saying it is shipped and will receive Wend. Not all chewey's fault, Just not worth the time and effort to do mail order.

No lid supplied to keep vial covered

Good price but no top so I use a top from a Pam that sits on it. Using for my cat.

Easy to Use!

First time using an injectable vitamin solution on my dog. It was easy to use with the syringes I had ordered. Seals up well, no leaks.

Large quantity for low price

Appreciate the great value for this item, however this quantity will last me 2 years at my dogs current dose. Just for purely aseptic reasons I wish it was available in smaller bottles so I could get a fresh bottle more often.
