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.
