Uzorak (Uzorak Analytical Lab)

Public information only

A Zagreb-based lab provides peptide testing with public pricing and sample reports. The lab is honest about lacking accreditation, though independent public evidence remains thin.

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.

Not publicly established

Who is behind the laboratory?

The public evidence does not currently establish a responsible issuer.

Boundary: Identity and responsibility do not establish analytical competence.

  • Neutral No business-register entry could be found. The laboratory does not claim one.
  • Neutral No named operating entity behind the brand could be documented.
  • Neutral The provided sources do not contain any data from official registers and no registered address can be determined.
  • 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.
  • Neutral Domain age ~236 days; years claimed by the website: None. The peptide division is young.
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

Reports from Uzorak Analytical Lab can be treated as coming from a real laboratory that is honest about its current limitations, but public evidence does not yet converge strongly enough to vouch for them at the highest level.

What Peptide Analysis Does Uzorak Offer?

Uzorak explicitly lists peptide analysis for compounds including Retatrutide, Tirzepatide, SS-31, and BPC-157, offering HPLC-UV purity and LC-MS analysis.

What Public Evidence Does Uzorak Provide?

The lab publishes sample reports, provides an online verification portal at uzorak.com/verify, and discloses mid-range pricing between 180.00 and 580.00 USD.

Does Uzorak Hold ISO/IEC 17025 Accreditation?

It holds no ISO/IEC 17025 accreditation and claims none - an honest statement that is the norm for a lab accepting private samples, not a mark against it.

Why Has Uzorak Not Reached 'Substantiated' Status?

The public evidence does not yet reach 'Substantiated' because corroboration across independent evidence dimensions remains narrow: the lab appears in none of the supplied forum, publication, press, complaint, or regulatory sources, and no independent community sentiment or scientific reference could be documented. This is a depth-of-evidence limit, not a negative finding.

What Are the Neutral Limits of This Public Review?

Separately, neutral limits on how far this public review can go include the absence of verified method-validation documentation for the relevant peptide methods and matrices, and no current independent evidence of actual analytical performance - neither is a mandatory gate nor a fault, only a boundary on what is checkable from public signals.

Are There Any Open Concerns About Uzorak?

No concrete open concern rises to a 'Watch' level.

What Do Domain Age and Website Signals Indicate?

The lab's domain is approximately 236 days old, no business-register entry or named operating entity could be found, and the website shows template placeholder content - all common for a small or startup lab and none implying wrongdoing. These are signals, not a verdict.

Below: the material this assessment is built on.

Accreditation

ISO/IEC 17025: Not accredited No entry found in registers. Lab itself claims no accreditation. Multiple secondary sources [2][3][14] confirm: not ISO/IEC 17025 accredited. Lab states it follows ISO/IEC 17025 principles where applicable, but acknowledges that full accreditation is complex for a pure research laboratory. No primary register query (HAA/ILAC) included in the sources.
