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.

Didn't notice too much at first but it was like every shot has been adding up and now that I'm about two months in I'm down 14 lbs and I've noticed that where I used to start losing my MOJO about 45 mins into my workout now I'm hitting that 60 min mark I want to way more often and I still have some left over for that extra cardio session later ha

Ordered from several other places and I prefer this over the others. The expiration date is reasonable and the medicine will not expire before I can use it all. I ordered from two other websites and one sent the vitamins with an expiration date that would leave me with expired medicine before I could use it all, the other had horrid customer service.

I just had one shot so far. Super easy to use, the needle is so small you don't even feel it. Some increased energy looking forward to continued increase in energy.

The B-12 shots have been great, they seem to give me more energy and have a focused mind while attending college. I would suggest giving them a try to anyone that could use a boost.
