Give him another day. If he doesn't get back with you by then, PM me again. Sometimes it can take a few days to get back with everyone because his general manager went on vacation and Z has a LOT of stuff to do by himself that he normally has help with or doesn't do himself. It can get to be quite a bit of work and there is no doubt he is bombarded with stuff to get done. Once per year, his manager, who helps him with a lot of daily duties, will go on vacation, but he should be back soon. Please forgive any oversights...I am sure it is not intentional. It's just that Z is probably doing the job of 3 people by himself right now, so mistakes are bound to happen. Things will be alright...I will guarantee you that. Z doesn't steal and he always sends what people order, so you can be at peace.
if ur looking for source u should look around the website then u'll get the clue on where to get em. But I thoroughly did my research on those sources and read a lot of materials before getting started. It's not simple as I thought, all stuff I needed and how to inject, what kind of syringe I need to buy. If you are not familiar with this then I suggest you read a lot of materials before you start. There are youtube clips that helps you how to inject as well. I don't want you to just jump in and make mistakes because I have some friends who didn't really do much research and just jumped in and got all F'd up. I get my stuff from Z. But heard naps were good too. That's all I can tell you. I can't give you URL or exact source since I don't know you well enough, but if u look around u'll get a clue on where to get em. good luck.
