Four separate review fields

Existing overall assessment: Substantiated

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

Partially substantiated

Who is behind the laboratory?

Specific identity details are substantiated, but the complete chain of responsibility is not public.

Boundary: Identity and responsibility do not establish analytical competence.

  • Positive KRS number 0000404918 confirmed in multiple sources, including KRS aggregators (krs-pobierz.pl, rejestr.io, BizRaport) and the company website lab4tox.pl
  • Positive The registered address ul. Marii Curie-Skłodowskiej 55/61, 50-369 Wrocław, Dolnośląskie, Poland is confirmed by Sąd Rejonowy dla Wrocławia Fabrycznej we Wrocławiu, VI Wydział Gospodarczy KRS.
  • Neutral No named real person could be documented for this laboratory; only an anonymous team.
Not publicly established

Is the procedure technically substantiated for peptides?

Public evidence does not currently substantiate competence for the relevant method and peptide matrix.

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

  • Positive The laboratory holds no accreditation and claims none. Absence of accreditation is the norm for a lab that accepts private samples; the honest statement of it is a signal.
  • Neutral No verifiable accreditation. For a laboratory that accepts private samples this is the norm, not a mark against it.
No public verification route

Can a report be traced back through the issuer?

No public verification route was found. This is normal and not a shortcoming.

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

  • Positive Lab4Tox itself has acknowledged that its certificates are being counterfeited by third parties and announced plans to introduce an electronic signature to mitigate this [7].
  • Neutral No public route for confirming a report with the issuer was found. This is neutral; public verification is an optional report-governance feature.
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

Reports from Lab4Tox carry multiple convergent public signals that support reliance for the categories the laboratory offers.

Legal and Registration Details

The laboratory operates under the legal name Laboratorium Badań Toksykologicznych Lab4Tox Spółka z o.o., registered in KRS under number 0000404918 since December 13, 2011. The registered address is ul. Marii Curie-Skłodowskiej 55/61, 50-369 Wrocław, confirmed by the District Court for Wrocław-Fabryczna. The domain lab4tox.pl has been registered since November 11, 2011, per WHOIS data through the registrar cyber_Folks S.A.

Services and Accessibility

Lab4Tox explicitly lists biologically active peptides (BAP) as a service category, confirming peptide testing is offered. The laboratory accepts private orders, as stated on its homepage and offer page.

Community References

On the MESO-Rx forum, Lab4Tox is referenced as an accredited lab alongside Simec. It is listed among labs used for CoA verification in a Reddit peptide community guide. On Evolutionary.org, a vendor shared a screenshot of Lab4Tox validating the authenticity of a cross-posted report.

Security and Accreditation

Lab4Tox has publicly acknowledged that its certificates are being counterfeited by third parties and announced plans to introduce an electronic signature to mitigate this. The laboratory holds no ISO/IEC 17025 accreditation and claims none, which is the norm for a laboratory accepting private samples and not a mark against it.

Public Evidence Limits

No named personnel could be documented for the laboratory; only an anonymous team is presented. No public pricing was found on the website, and no public route for confirming a report with the issuer was found. These absences are neutral public-evidence limits, not faults.

Conclusion

No concrete open concern rises above the neutral signals. These are signals, not a verdict.

Below: the material this assessment is built on.

Accreditation

ISO/IEC 17025: Not accredited No entry found in FDA ASCA, DAkkS, UKAS or A2LA. Secondary source Peptigrity [3] explicitly states: 'Lab4Tox is not currently listed as ISO/IEC 17025 accredited'. PCA (Polish Accreditation Body) was not searched in the sources - accreditation there remains unconfirmed, but also not ruled out. Lab4Tox itself does not claim any accreditation on its website [2][10].
