I had a vial of test cyp, and had a pretty good feeling it wasn't legit. I only did 1 injection and before I do another I wanted to know for sure what the deal with it was. So I loaded 2CC in a syringe and put it in the freezer. All it did was get thick and there was no crystallization or anything.
So after that I decided to throw the whole vial in the freezer and still same thing... so it's pretty safe to conclude its 100% fake now right? I mean there was not the slightest trace of crystallization... just the oil getting thick!
