I believe in your or my hands they are illegal unless of cours ya got a heard of steer you never told us about LOL. Just like how its legal for me to have tramadol from the vet if its a scrpt for my dog, but its not legal for me to just have tramadol. If you find it from a legit cattle supply store then Id say no doubt they are real, but just like anything on the black market who really knows. They arent dumb they know why you want it. Remember at one point Cocaine and Queludes were legal , at one point I could buy as much sudafed as I wanted. Now if I buy sudafed my name gets registered in a data base and if I buy more that month I get flagged. In the end I dont really know, Im just guessing if they got rid of it from the cattle industry cause they knew it was being used for tren then something is up with you getting your hands on it .
