RUO supplier
Official catalog, verification, and batch-status pages reviewed
Deep research review
Nexus Laboratory exposes a public catalog with explicit finalized and pending record states. Its evidence-boundary page says the public records are normalized Nexus summaries and do not expose the originating laboratory, source reports, report identifiers, accreditation scope, or raw files.
What this review did not check: The public records are normalized Nexus summaries, not original laboratory reports.
Active storefront observed

Findings
Dated Site State
The site displayed 95 catalog records, 48 finalized public records, 47 pending records, and a 99.67% average of reported HPLC values.
Limit: These are site-calculated values and should remain date-stamped.
Explicit Evidence Boundary
The verification page states that public records do not identify the originating laboratory, accreditation scope, source report, report identifier, or raw instrument files.
Limit: The originating evidence cannot be independently inspected from the public record.
Public Status Aware Catalog
Product pages distinguish finalized COA records from certificate-pending records before checkout.
Limit: A finalized status does not expose the originating report.
Public Normalized Summary
Finalized records show lot-specific fields such as HPLC purity, retention time, expected and observed mass, and additional panels when present.
Limit: The records are Nexus summaries, not original laboratory reports or raw traces.
Normalized Sample Record
BPC-157 lot APX-2026-0405-B reports 99.65% RP-HPLC purity, 12 minute retention time, 1419.53 Da expected mass, and 1419.50 Da observed mass.
Limit: The originating laboratory report is not public.
Normalized Sample Record
Retatrutide lot APX-2026-0428-R reports 99.49% RP-HPLC purity, 17.8 minute retention time, 4731.33 Da expected mass, and 4731.50 Da observed mass.
Limit: The originating laboratory report is not public.
Search limits
Limited regulatory search
No exact-name FDA warning letter, recall, or enforcement page attributable to this supplier surfaced in the limited FDA-site search.
Limit: Search results included unrelated Nexus entities. Search absence is not regulatory clearance.

Observable documentation fields
This measures fields in normalized public records. It does not score product quality, sterility, legal compliance, or suitability.
Normalized batch records
Each row becomes a stacked record on smaller screens. Coverage means the field appears in the source record. It is not a Peptide Report pass or independent reproduction.
| Product | Batch | Laboratory | Date | Methods | Fields present | Record |
|---|---|---|---|---|---|---|
| GHK-Cu 50 mg research material | NEX-GHK-CU-2026-0035 | Not named in the normalized record | Jan 1, 2026 | HPLC, Mass spectrometry | identity, purity | Source report |
Observed catalog records
The public COA pages are normalized supplier summaries. The reviewed pages did not expose the originating laboratory, original report IDs, or raw report files.
Profile ownership: unclaimed. Company representatives will be able to propose identity and catalog updates without changing editorial or regulatory records.
These secondary directories helped identify the company. Their rankings and verification labels are not adopted by Peptide Report.
