Four separate review fields

Existing overall assessment: Listed

The overall assessment is not an average of these four fields. Each field answers a different question and cannot offset another.

Substantiated

Who is behind the laboratory?

A responsible legal entity and its leadership or operator are publicly substantiated.

Boundary: Identity and responsibility do not establish analytical competence.

  • Positive LABS & TECHNOLOGICAL SERVICES AGQ SOCIEDAD LIMITADA (CIF/NIF B91607127) is registered in the Mercantile Registry of Seville, Spain.
  • Positive At least one named key person is independently attributed to this laboratory: Estanislao Martínez (+3 weitere).
  • Positive A public LinkedIn profile is on record for Estanislao Martínez.
  • Positive Maria Pena has held the Lab Director role at AGQ Labs USA since May 2012.
  • Neutral Registered address for Labs & Technological Services AGQ SL is not available in the supplied sources.
Partially substantiated

Is the procedure technically substantiated for peptides?

Specific method or process evidence exists, but the full method-by-matrix contract is not public.

Boundary: Lack of accreditation is normal here and is not a negative signal.

Signal profile - Counts show composition, not a score. Core evidence 1 Supporting evidence 2 Boundary 2 Contradiction 0
  • Positive ISO/IEC 17025:2005 (IAS): accreditation active.
  • Positive The laboratory names concrete instrumentation: GC-MS/MS & LC-MS/MS.
  • Positive AGQ Labs origin is in agri-food, pesticide residue testing, and environmental analysis. Multiple ISO 17025 accreditations via IAS confirm competence in chromatography-based analytical testing (GC-MS/MS, LC-MS/MS), which is a transferable analytical competence context though not peptide-specific.
  • Neutral ISO 17025 is claimed, but no entry in the accreditation body's own register could be cited; the claim can neither be verified nor refuted.
  • Neutral None of the IAS accreditation scopes (TL-509, TL-972, TL-923, TL-1095) or other documented scopes list peptide analysis, peptide identity verification, peptide quantitation, HPLC purity testing, or impurity profiling. The Life Science page mentions pharmaceutical QC broadly but provides no accreditation scope for peptide testing. Source [17] advertising peptide purity testing is from Ethos Analytics, a different lab.
Verification offered

Can a report be traced back through the issuer?

A laboratory-controlled form or registry is available, but no qualifying specific report was confirmed.

Boundary: Report confirmation establishes neither analytical competence nor the contents of an individual vial.

  • Positive The laboratory offers a verification form. We could not confirm a real report through it, so this counts as an offer, not as proof.
Not publicly established

Has actual measurement performance been checked externally?

No suitable independent evidence of actual measurement performance was publicly established.

Boundary: Testimonials, report volume and average purity values are not external performance evidence.

No public signals in this review field.

Our honest take

AGQ Labs is a registered Spanish laboratory with verified institutional identity and documented analytical competence, but currently lacks public evidence of a peptide-specific testing offering.

AGQ Labs: Registered Spanish Laboratory with ISO/IEC 17025 Accreditation

AGQ Labs operates as a registered Spanish legal entity under the name LABS & TECHNOLOGICAL SERVICES AGQ SOCIEDAD LIMITADA (CIF B91607127, registered with the Mercantile Registry of Seville). The laboratory holds active ISO/IEC 17025:2005 accreditation through IAS and names leadership with public profiles, including founder and Executive President Estanislao Martínez and AGQ Labs USA Lab Director Maria Pena, who has held that role since May 2012. The lab discloses concrete instrumentation, specifically GC-MS/MS and LC-MS/MS.

Does AGQ Labs offer a report-verification service and what are its documented testing areas?

AGQ Labs provides an online report-verification portal at agqlabs.es/verify, which we could not test with a real report and therefore count as an offered process rather than proven functionality. Its documented competence is in pesticide residue, agri-food, and environmental chromatography-based testing - a transferable analytical foundation, but not peptide-specific.

Evidence Limits: No Peptide-Specific Offering or Accreditation Scope

None of the IAS accreditation scopes (TL-509, TL-972, TL-923, TL-1095) list peptide analysis, identity verification, quantitation, or purity testing. The lab's Life Science page references pharmaceutical QC broadly without a peptide-specific scope. Additionally, neutral public-evidence limits apply: we have no verified method-validation data for peptide-relevant matrices, no independent performance evidence, and no community reputation footprint in the peptide context. The lab's website is Spanish-only and pricing requires a contact form.

Why is AGQ Labs rated 'Listed' instead of 'Substantiated'?

AGQ Labs holds a 'Listed' rating rather than 'Substantiated' because no public signal evidences a peptide or research-chemical testing offering. This is an open question about scope, not an indication of incompetence. No concrete open concern - such as a complaint pattern or a refuted accreditation claim - is on record. These are signals, not a verdict.
