TCI: common questions
Is TCI 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 83 TCI 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 TCI #10 of 30 ranked vendors, at market on our score. Results on file run from Jun 2024 to Aug 2026.
Has TCI been third-party tested?
Yes. We hold results for 83 TCI vials from 72 lab reports, tested by Chromate, Forever Young Pharmacy, Janoshik, Krause Analytical, Peptide Test, SR Biolabs, Vanguard. 31 of those reports were paid for by buyers or group tests; 41 were commissioned by TCI itself, verified at the lab, and count at half weight in the score.
Are TCI vials dosed correctly?
Across 80 vials where the lab measured the amount, the median TCI vial held +10.7% compared with its label. 0 of 80 held more than 10% less than the label said.
How pure is TCI?
The median TCI vial tested at 99.75% purity across 83 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 TCI 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 TCI 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.
