Thank you, researcher.

The page in front of this is the actual certificate of analysis for the vial in your box. Same batch ID on the label, the seal, and that document. If the three don't match, do not use the product, and email me.

The lab partner who tested this batch is named on the front of the certificate. Their contact information is on our website. You are welcome to verify with them directly — that is exactly why we name them.

Every batch we sell is independently tested and dated. Every claim on our site can be traced to a piece of paper with a batch number on it. If you find one that can't, email me and we will either prove it or remove it within seven days.

If anything in this batch is not what we said it was — wrong identity, purity below spec, anything — email me at founder@ledgerbioscience.com and we will refund the order and investigate publicly. We mean that.
