Zyntro Analytical Lab Solutions

Public information only

A US laboratory provides mail-in peptide purity testing using LCMS. It publishes its pricing and offers an online portal for verifying reports. However, there is no independent confirmation of its operations or accreditation.

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.

View 4 signals and their evidence
Signal profile - Counts show composition, not a score. Core evidence 0 Supporting evidence 0 Boundary 4 Contradiction 0
  • Neutral No business-register entry could be found. The laboratory does not claim one.
  • Neutral No registered address is documented. The contact page states a lab address will be provided after inquiry; no address appears in the supplied excerpt.
  • Neutral No named real person could be documented for this laboratory; only an anonymous team.
  • Neutral Website claims a Texas-based lab (United States), but no official registered jurisdiction is documented in any provided source.
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.

  • Positive The laboratory names concrete instrumentation: LCMS-DAD.
  • Neutral No verifiable accreditation. For a laboratory that accepts private samples this is the norm, not a mark against it.
  • Neutral ISO 17025 is presented on the laboratory's own website, but no entry in the accreditation body's own register could be cited; the claim can neither be verified nor refuted.
  • Neutral Domain age ~277 days; no claimed years on the website. Very young peptide testing division.
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 Zyntro Analytical Lab Solutions cannot yet be independently corroborated beyond what the laboratory says about itself.

On the positive side, Zyntro explicitly offers peptide purity testing by LCMS with DAD, publishes a mid-range price list ($25-$300 USD), accepts private mail-in samples from individuals, names concrete instrumentation, and provides an online report-verification portal at zyntrotest.com/search.html. These are concrete, checkable service signals.

The public evidence does not yet converge to a 'Substantiated' rating because every corroborating signal originates from Zyntro's own website: no independent mention of Zyntro or ZyntroTest was found across 18 supplied sources including community forums, scientific literature, press, and regulatory records.

  • The domain is approximately 277 days old.
  • No business-register entry exists.
  • No named personnel are documented.
  • No verifiable physical address is published.
  • An ISO 17025 claim appears on the site but could not be confirmed in any accreditation body's register.

Separately, and without fault: this review could not assess verified method competence for the relevant matrix or current independent analytical performance, as no such public material is available - these are neutral depth limits, not negative findings.

No concrete open concern beyond the absence of independent corroboration is on record. These are signals, not a verdict.

Below: the material this assessment is built on.

Accreditation

ISO/IEC 17025: Not accredited Lab explicitly states 'ISO 17025 Accreditation in Progress' on website [8][10]. No register entry found in A2LA [11], FDA ASCA [2], or AIHA [15]. No accreditation body named, no certificate number, no timeline provided. Third-party directory lists ZyntroTest without ISO badge, unlike a competitor [13].
