ASC: common questions
Is ASC 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: 2 of 36 ASC 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 ASC #18 of 30 ranked vendors, at market on our score. Results on file run from Oct 2024 to Mar 2025.
Has ASC been third-party tested?
Yes. We hold results for 36 ASC vials from 27 lab reports, tested by Janoshik, Peptide Test, SR Biolabs. Each result comes from a lab report a buyer paid for, not from a certificate the vendor supplied.
Are ASC vials dosed correctly?
Across 35 vials where the lab measured the amount, the median ASC vial held +4.5% compared with its label. 3 of 36 held more than 10% less than the label said.
How pure is ASC?
The median ASC vial tested at 99.71% purity across 35 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 ASC 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 ASC 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.
