Colmaric Analyticals

Public information only

A long-standing US analytical lab with verified leadership and disclosed instrumentation, currently flagged because its advertised certificate-verification page returns a 404 error.

Watch profile: widely used, but with unresolved signals below. Popularity is not verification - read the signals and their sources. Think this rating is too strict? Perhaps. But a lab should mind the details - when it does not, that too is a signal.

Four separate review fields

Existing overall assessment: Watch

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.

Signal profile - Counts show composition, not a score. Core evidence 1 Supporting evidence 2 Boundary 2 Contradiction 0
  • Positive At least one named key person is independently attributed to this laboratory: Collin Thomas.
  • Positive A public LinkedIn profile is on record for Collin Thomas.
  • Positive Collin Thomas's tenure as President at Colmaric Analyticals since September 2008 is evidenced by his personal LinkedIn profile [18], corroborated by the company website [17] identifying him as President and CEO.
  • Neutral No business-register entry could be found. The laboratory does not claim one.
  • Neutral LinkedIn profile lists St. Petersburg, Florida as location, while commercial directories (D&B/BBB) point to Goodlettsville, Tennessee. Neither is verified as an official registered office.
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.

View 3 signals and their evidence
Signal profile - Counts show composition, not a score. Core evidence 0 Supporting evidence 1 Boundary 2 Contradiction 0
  • Positive The laboratory names concrete instrumentation: HPLC-UV, LC-MS.
  • Neutral No verifiable accreditation. For a laboratory that accepts private samples this is the norm, not a mark against it.
  • Neutral ISO/IEC 17025:2017 is claimed, but no entry in the accreditation body's own register could be cited; the claim can neither be verified nor refuted.
Verification route contradicted

Can a report be traced back through the issuer?

An advertised route or the issuer assignment conflicts with the substantiated check.

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

  • Watch The laboratory advertises certificate verification, but the advertised page does not exist (HTTP 404 when fetched).
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 Colmaric Analyticals carry meaningful but not fully convergent public evidence.

Several solid signals support the laboratory's existence and operational history:

  • The domain colmaricanalyticals.com has been registered since May 14, 2008.
  • Collin Thomas is independently verified as President and CEO via his personal LinkedIn profile, which lists his tenure starting September 2008, corroborated by the company website.
  • The laboratory discloses concrete instrumentation including HPLC-UV and LC-MS.
  • It lists specific peptide analytes such as BPC-157, TB-500, semaglutide, and tirzepatide.
  • Community sources describe Colmaric as an established third-party testing lab, and a forum user on Evolutionary.org reported calling the laboratory directly to confirm it conducts third-party testing and encourages customers to verify individual lots.
  • The laboratory's Florida LLC registration (L21000153402, filed April 9, 2021) is checkable on Sunbiz.

The public evidence does not converge to the highest rating for one concrete reason: the laboratory advertises a certificate-verification page on its website, but that page returns HTTP 404 when fetched, meaning the single mechanism by which a customer could independently confirm a reported result is currently non-functional. This is the specific open concern that places the laboratory under Watch rather than at a higher tier.

Separately, the claimed ISO/IEC 17025:2017 accreditation could not be located in any accreditation body's register, and no business-register entry predating the 2021 Florida filing was found - but for a laboratory whose public ordering route addresses business customers, these absences are normal public-evidence limits, not faults. An address inconsistency exists between LinkedIn (St. Petersburg, Florida) and commercial directories (Goodlettsville, Tennessee), neither confirmed as the official registered office. These are signals, not a verdict.

Accreditation

ISO/IEC 17025:2017: Claimed, unverified Colmaric Analyticals claims ISO/IEC 17025:2017 accreditation (No. 86258) through Perry Johnson Laboratory Accreditation, Inc. The claim appears on the lab's own website as well as in third-party directories. No official PJLA registry entry or active certificate was found to verify status or defined scope. Peptide identity/purity testing via HPLC-UV and mass spectrometry is associated with the lab by third-party guides but is not confirmed by a primary scope document.

  • Positive The domain colmaricanalyticals.com has been registered since May 14, 2008, according to WHOIS records via Bluehost Inc.
  • Positive Colmaric is cited as one of the three most prominent third-party testing labs in the research peptide community, described as 'The Established Player' and a 'more traditional analytical laboratory' operating from the United States [11, 18]. A forum user on Evolutionary.org reported calling Colmaric to verify their legitimacy, confirming they conduct third-party testing and encourage customers to verify individual lots/batches [14].
  • Neutral Two separate peptide vendor review sites (proxivalabs.com and peptidepick.com) both list the identical set of three analytical labs - Janoshik Analytical, MZ Biolabs, and Colmaric Analyticals - as the trusted third-party testing labs for peptide vendors.
