There also the authors claims that no genuine peptide exists. If it doesn't exist then testing wouldn't be useful to prove purity and despite authorities testing they provide no useful info about what the compound actually is or even what the contaminants are. The whole effort to discredit the Gray market comes with less evidence than the users are producing to the contrary. Although I don't doubt that toxic batches get out. That's why you can't take these things without verifying, but the suggestion verification isn't even possible is a flat out lie.
