Why people switch to us

A lab report on a vendor's site can be completely real and still be for a different batch than the one you got. Buyers in the peptide forums see it all the time: "they just recycle old COAs. They sell out of a product then restock weeks later but the COA stays the same."

Sometimes it's worse. In July, CBS News bought a vial that came with certificates the named lab said it never issued, and weeks later a peptide company owner was sentenced to 70 months in federal prison for forging the lab reports he sent to customers.

So we don't ask you to trust our PDF. Every report is hosted by Accumark Labs, where we can't edit it, and you can open it there before you order.
