Great service! Affordable. Half the price of a local provider and none of the scheduling and time wasting.

So easy to use and pretty painless Had previously used a doctor’s office to get B12 shots every other week but, doctor has since retired and the nearest new doctor is a good distance away These B12 RX shots are much better I feel less fatigued and the effects of these shots last longer

This product does as its advertised. My work is very physical and it has really helped me with energy. The needle is very fine and totally painless.

I love the energy the shots give me. I have just taken my 3rd shot and I can definitely notice a difference in energy when I am due for another shot. I am more active than I have been in years. It's also very convenient that the injections are premeasured and the needles are small so I barely feel anything when I take the shot.

I used your product 3 times and I have to say I feel better than I have in years . I am so glad I chose to use your product. I'm full of energy, feel more focused, and have been sleeping better. I love the self injector, it's easy and I don't feel a thing. Thanks for offering such a great product.

I had surgeries many years agoo and a lot of my small intestine was taken out so I don't get B vitamins from the foods I eat. I can't do pills because that's still not going to be absorbed, so I thought I'd give the B12 shots a try. I'm still getting built up, but can most definately feel the difference these shots are making in my life. I'm a forever customer...... Thanks SO much, and God bless you guys!!

The cold chain shipping used to insure a delivery that maintains products potency and strength speaks volumes about the company’s professionalism. Just started the treatment so to early to state results but am looking forward to improved health. Thankful this product is . Available.

So far I am very happy with B12rx. My concerns over defective syringes (2) out of 5 have been addressed. The B12 injections are so much better than what I have previously used although they are a bit more expensive. But overall, I am extremely happy with the company and the product.

I had issues keeping my B12 levels up. I was supplementing regularly, but every time I got bloodwork done, my B12 levels were still low. It turns out I wasn’t absorbing B12 properly through oral supplements. I'm so glad I found B12rx — I'm finally able to maintain healthy levels. What I like most is that the shot is virtually pain-free, and I only need to do it once a week. It's made a major improvement in my overall well-being.

Love these B-12 shots. Potency is as advertised and using the Auto injector makes the process simple.

I love the convenience of the pre-filled syringes and that they are individually packaged. My only feed back is the needles need to be the smaller “insulin” type as the ones included tend the hurt and leave bruises

So far I have found that on days when I take the injections, as well as the 2nd day after, I sleep much better, feel more energetic and metally sharper. Im scheduled now to inject every three days. Im going to change that to every other, day for a while.
