TFC: common questions
Is TFC 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: 5 of 15 TFC 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 TFC #30 of 30 ranked vendors, below market on our score. Results on file run from Feb 2025 to Aug 2026.
Has TFC been third-party tested?
Yes. We hold results for 15 TFC vials from 7 lab reports, tested by Freedom Diagnostics, Janoshik, MZ Biolabs, Peptide Test. Each result comes from a lab report a buyer paid for, not from a certificate the vendor supplied.
Are TFC vials dosed correctly?
Across 11 vials where the lab measured the amount, the median TFC vial held +20.6% compared with its label. 3 of 12 held more than 10% less than the label said.
How pure is TFC?
The median TFC vial tested at 99.72% purity across 6 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 TFC 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 TFC 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.
