QST: common questions

Is QST legit?

We can't vouch for any vendor as a business, and we don't sell or recommend products. What we can show is what buyers' independent lab tests found: 0 of 22 QST vials on file failed, meaning they were empty, under 95% pure, more than 20% under the label or more than 50% over it. That places QST #3 of 30 ranked vendors, above market on our score. Results on file run from Jun 2025 to Aug 2026.

Has QST been third-party tested?

Yes. We hold results for 22 QST vials from 13 lab reports, tested by Janoshik, Peptide Test, Uzorak. Each result comes from a lab report a buyer paid for, not from a certificate the vendor supplied.

Are QST vials dosed correctly?

Across 11 vials where the lab measured the amount, the median QST vial held +7.3% compared with its label. 0 of 11 held more than 10% less than the label said.

How pure is QST?

The median QST vial tested at 99.64% purity across 22 vials with a purity result. We count anything under 95% as a failed vial, and a vial at 99.5% or higher gets full marks for purity.

Does QST pay to be listed or ranked?

No. VendorVerify sells nothing and takes no money from vendors. No affiliate links, no coupon codes, no paid rankings. A vendor's place comes only from lab results.

Will my QST vial match these results?

Not necessarily. A lab report describes the vials that were tested, and batches differ. A clean record lowers the odds of a bad vial but doesn't rule one out, which is why newer reports count for more in the score.
