Confessions of a beginner

My first vial also came from a random source and cost as much as an entire kit. I did not even know what a COA was at the time. I bought bac water online, got the rest of the supplies, reconstituted it and stored it in the fridge. I am grateful because it taught me the basics before I found better sources. I eventually discarded that vial. The gray market is called gray for more than one reason, including never being completely sure what is in the vials.
