HYB: common questions
Is HYB 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: 1 of 4 HYB vials on file failed, meaning they were empty, under 95% pure, more than 20% under the label or more than 50% over it. HYB has 4 lab reports on file, fewer than the 5 needed to be ranked, so treat this as early data. Results on file run from May 2025 to Dec 2025.
Has HYB been third-party tested?
Yes. We hold results for 4 HYB vials from 4 lab reports, tested by Janoshik. Each result comes from a lab report a buyer paid for, not from a certificate the vendor supplied.
Are HYB vials dosed correctly?
Across 3 vials where the lab measured the amount, the median HYB vial held +12.8% compared with its label. 1 of 4 held more than 10% less than the label said.
How pure is HYB?
The median HYB vial tested at 99.74% purity across 3 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 HYB 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 HYB 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.
