First time shopping with K4L last week and I have nothing but good shit to say.. Pack was both ordered and delivered in 3 days, I had my tracking number I think an hour after paying, dudes really on his shit. First dose was yesterday did 2iu and today even though a small amount I still split my ius morning fasted the about 7 hours later making sure I hadn't ate at least an hour before an A hour after. Top shelf, delivery, customer service, knowledge of product and from what that man's lab work shows us top shelf GH. Much Respect K4L and I appreciate the blessing my bro
