Be careful with the energy drinks man. I have a buddy who has a kidney issue and the doc told him to stay off of them. If he has one, he has to water it down in half and drink it slowly. Not sure what is in it that causes the issue but thought I would pass it along.
I would just get some legit product from Umbrella Labs so you know it is legit. I would hate for your first experience with a PED to be shit because the source was fake.
