Legitimacy review
Seven Summit Research Supply certificates match their QR-linked ACS originals byte for byte. They report identity and purity, while nominal strength and net peptide content are blank.
ACS identifies its facility at 721 Cortaro Drive, Sun City Center, Florida. The reviewed certificates name Aixia Sun as laboratory director and principal scientist. ACS markets nationwide peptide analysis; its service page links to peptides.mahiportal.com, the same host used by the inspected certificate QR codes.
Seven byte-identical originals and a public service page linking directly to the same report platform.
ACS advertises ISO and validated-method credentials. This review did not establish an accreditation scope explicitly covering the peptide methods in these seven certificates. A corporate or cannabis-testing credential should not be presented as peptide-specific accreditation.
The published menu offers HPLC purity, mass spectrometry, LAL endotoxin, ICP-MS metals, GC-MS solvents and stability work. ACS advertises 9–11 business days and HPLC testing from $150, with a quote and shipping instructions before intake.
This review establishes the public service and document evidence. It includes no blind-sample proficiency study or independently measured customer-service dataset.
The inspected reports cannot verify a retail strength because nominal mass and measured content are blank. Document and public-source review completed October 9, 2026; no laboratory visit or blind sample submission.
All seven complete Summit PDFs agree byte for byte with their QR-linked public originals. The accession number, Summit client name, batch and measurements are preserved. The current ACS service page independently links to the same Mahi Portal host.
The certificates name mass identification and report purity using LCMS-UV. Their nominal-strength and net-peptide-content fields are blank. The historical MOTS-c result is 93.044%; this remains a measured result rather than a passing purity check.
A quoted service can include content or contamination testing, but that scope must appear on the issued report. The reviewed Summit ACS files contain neither quantified peptide content nor endotoxin results.
The website advertises ISO credentials and guideline-based methods. This review has not confirmed a peptide-specific accreditation schedule naming these methods. The specific issuer-file matches remain valid independently of that unanswered scope question.
The retained certificates were issued in June and July 2026. The current website identifies ACS with Smithers and advertises nationwide intake. Current service descriptions do not retroactively add panels to earlier certificates.
COA verification
Use the exact QR-linked Mahi Portal record and compare the downloaded PDF with the vendor copy.
Result handling
The specific issuer file agrees on the report identifier, client, sample and results.
Reserve no-match for an explicit negative response from a functioning issuer lookup.
Retain material differences in client, compound, batch, amount or results.
An inaccessible portal leaves verification unresolved.
Outside the fixed automated checker roster; these reviews do not expand that roster.
Keep the full file and printed results visible without claiming an issuer match.
Certificate structure
The seven reviewed ACS files are complete one-page PDFs.
Reviewed ACS reports show mass identification and purity; nominal and net peptide content are blank.

Frequently asked questions
Report service confirmed. Seven Summit Research Supply certificates match their QR-linked ACS originals byte for byte. They report identity and purity, while nominal strength and net peptide content are blank.

Peptide-specific scope not confirmed. ACS advertises ISO and validated-method credentials.

The reviewed sources did not establish that vendors can purchase a passing result from ACS Peptide Testing Labs. That is not an audited independence guarantee: sample selection, who pays, publication rights, blind-testing controls, and correction history still matter.
Supplier-submitted samples do not establish custody of every retail vial.
An inaccessible portal leaves verification unresolved.
