It's difficult to know these days what type of company you're ordering from – but I was extremely happy with being able to chat with humans to get all of my questions answered immediately… no call backs or return emails needed. I felt good about the pricing and even got a 20% discount. I received my product 3 days after ordering, complete instructions were easily found online and I followed them to the letter. Took my first dose last night… (a) injection didn't hurt at all. (b) had zero reactions at the injection site (c) slept better last night than I have in a really long time (d) had no adverse side effects last night and I've experienced none today (e) I feel absolutely amazing today, I'm breathing a lot better; I have a crazy amount of energy with no jitters; I'm not hungry at all and haven't been so far today (it's 9:54 am) but I will definitely force myself to eat a healthy lunch & dinner and drink water all day & night which is usual… mental clarity today is off the charts… productivity is off the charts. I AM THRILLED WITH MY PURCHASE AND CAN'T WAIT TO SEE RESULTS AT THE END OF 90 DAYS.
