I am on my third dosage of b12 and I honestly cannot tell any difference. I am disappointed because for the cost I was looking for a good pick up in my energy as advertised... Did not happen! I would be happy to leave a better review if it works!

Product is great, does exactly what it claims. I purchased the all singing and dancing version and can attest that my energy levels are up, I’ve gone down 5lbs in 24 days and feel great.

I am on shot #2 of the B 12 rapid burner and feeling good with a boost of energy! Not sure about rapid burner but I am not having urges of hunger so far. Looking forward to seeing some results and glad for more energy.

I really want to love the product. It’s really easy to use. But I have chronic fatigue and I’m not really seeing much of an improvement yet. I will definitely re-order because I want to give it a deserved amount of time before I can make a judgment.

I had a terrible reaction to my first two doses and can't get anyone from your company to answer me. I have called and emailed all week and still no response. The negative side effects are bad enough that I am afraid to try another dose. Very disappointed in the product and customer service, lack of response.

Sherilyn, Thank you for taking the time to post this review! How long have you been using our shots? It is important to remember that although some users will notice results right away this can vary from person to person depending how your deficiency has impacted your health. For many sub-optimal b12 manifests in the way of malformed hemoglobin, which means your body cannot carry adequate amounts of oxygen within your red blood cells leading to a whole host of issues, especially fatigue and problems with focus. Once your body reaches optimal b12 levels it will take approximately 90 days to completely refresh/ renew your red blood cells and the hemoglobin within them. If you still haven't noticed a change at this point, please reach out and we will make sure you are taken care of. We want nothing more than 100% customer satisfaction!

I am happy to have found a Doctor for my vitamin shots to use in the comfort of my home. The process is really fast and safe. I work full time and I don't have much time, shipping has saved me a lot of this. The procedure for how to use it is really easy and fast, you use an insulin syringe that is very small and does not hurt, the injection is subcutaneous, if you prefer you can use the autoinjector (You pay only once). The syringes come prefilled with the medication in separate, sealed envelopes.
