ABC testing finds black-market retatrutide vials way overdosed, not just underdosed

ABC got three black-market retatrutide vials independently tested and two of them came back significantly stronger than the label claimed. So it is not just the usual problem of peptides being underdosed or full of bac water, the actual concentration can be way higher than you think you are pinning.

Honestly this is what worries me most about the grey market scene. Underdosing wastes your money and your time, but overdosing is the one that can actually hurt you, and most of the harm stories I have read trace back to concentration surprises rather than the peptide itself being toxic. I reckon this needs to be talked about more instead of the usual "just get your bloods done" advice, because if the vial is mislabelled by that much no amount of personal research keeps you safe.

Has anyone here actually sent a grey-market vial off for third party testing, and was the result anywhere near the label?
