I am happy with the product and the packaging and the injector. I am unsure if I notice anything after 3 injections in 9 days. I have not had urine discoloration and I have not felt an energy boost, so it makes me wonder, but I most likely need to give it more time. The only issue I had was there was notification that medicine shipped, my account portal showed it had not shipped and when I sent an email to ask for an update nobody replied.
