Yes, with caveats. PeptidePrices rates Vantyx Research 6/10. Four of five Freedom Diagnostics reports match the issuer file index, but they cover only four of 25 current comparison rows. The fifth, a Glow blend report, has no live issuer record and names different components from the product page. The store does not identify a legal entity or street address, and its policy pages retain template placeholders.
Evidence summary
Vantyx Research COAs and evidence
Vantyx has a live store and five public Freedom reports. Every report names Vantyx Research as the client, and four search codes matched Freedom Diagnostics' public file index.
Coverage is limited. The five reports cover four of the 25 catalog rows, one report has no issuer record and no listing control, and the policy pages contain unresolved template text. Match the exact product, strength, and lot to a report. Code peptideprices gives customers 15% off.
01
Vantyx Research COA tests
The vendor COA page has ten links that resolve to five distinct Freedom Diagnostics reports. PeptidePrices retained all five. Four search codes resolve in the laboratory file index and the issuer-hosted files match. Every report prints identity, purity and measured content; none shows endotoxin, sterility, heavy-metals or microbial results. The Tesamorelin 10mg report lists 97.203% purity. The Glow report has no issuer index entry and its official file URL returns 404, so it remains a checked file without a verified badge.
02
Vantyx Research reviews
Four reports match a current row exactly: Retatrutide 10mg, GHK-Cu 100mg, a CJC-1295 No DAC and Ipamorelin blend, and Tesamorelin 10mg. That is four of 25 comparison rows. The Glow certificate lists GHK-Cu, Ac-SDKP and BPC-157, while the product page lists GHK-Cu, BPC-157 and TB-500; it has no listing control. The PeptidePrices COA library preserves each report and its status.
03
Vantyx Research checkout and company
Trustpilot showed 4.0/5 from nine reviews on October 3: eight five-star and one one-star. July 30 feedback praises speed and communication; July 15 feedback describes dispatch delay, unanswered support and dissatisfaction. Six April 13 posts form most of the earlier positive cluster. This small sample does not resolve Glow’s component/issuer conflict. Vantyx states Florida shipping without a named owner, legal entity or street address. Cards, bank payments and wallets remain published, while policy placeholders and conflicting final-sale clauses remain unresolved. The owner’s 6/10 rating stays.

Watch-outs
Five reports cover four of the 25 catalog rows for a store that lists 31 products
Freedom's public file index returned no record for the Glow report, and its issuer file URL returns HTTP 404
The Glow certificate prints GHK-Cu/Ac-SDKP/BPC-157 while the product page describes GHK-Cu/BPC-157/TB-500, so that report has no listing control
Blend totals do not reconcile with the printed labels: the Glow components sum to 59.17 mg against 70 mg, and the CJC-1295 and Ipamorelin components sum to 11.86 mg against 10 mg
The Tesamorelin report lists 97.203% purity
The reports carry no endotoxin, sterility, heavy-metals, residual-solvent, or microbial result
The site does not name an owner, legal entity, or street address
The shipping and refund pages contain template placeholders
The refund page permits some claims, but the terms state that all sales are final
Trustpilot has only nine reviews and includes one recent shipping and product complaint
