GenX Peptides was founded in 2013 and is one of the longest-operating research peptide vendors in the US market. The site at genx.bio is publicly accessible. The About page describes HPLC and mass spectrometry testing and states the company is an "accredited quality assurance provider" - no testing laboratory is named anywhere on the site. Third-party review sources identify MZ Biolabs as the testing lab, but this is not confirmed on the vendor's own pages. No public COA library is hosted on the site. GenX was added as a named respondent in Eli Lilly's USITC trademark investigation regarding tirzepatide false designation of origin on May 21, 2024 - the same Inv. No. 337 investigation in which Strate Labs was also named. The 13-year operational track record is the strongest single scoring factor for this vendor, but is materially offset by the USITC enforcement context and the absence of any publicly verifiable documentation.
| Dimension | Max | Notes | Score |
|---|---|---|---|
| Third-Party Testing Practice | 30 | HPLC and mass spectrometry testing described on the About page as the standard testing methodology. The About page describes GenX as an "accredited quality assurance provider" without naming the accrediting body. Third-party review sources (Peptide Protocol Wiki) identify MZ Biolabs as the testing lab. MZ Biolabs is not named on the vendor's own site. VTS credits the externally identified lab partially; the absence of lab disclosure on the vendor's own pages limits the score. MZ Biolabs standard service excludes sterility and endotoxin testing. | 12/30 |
| Batch Traceability & Verification | 20 | No public COA library, no lot-searchable database, and no COA examples visible on the public-facing site. Third-party review sources note that COAs are available, but no batch traceability system is accessible publicly. Partial credit for the stated testing program and the external identification of MZ Biolabs, which has a verifiable DEA registration. | 6/20 |
| COA Accessibility | 15 | No public COA library hosted on genx.bio. No COA examples on product pages. COAs appear to be provided with orders per third-party review sources. Request-only or with-order COA access scores equivalently to email-on-request under VTS methodology. Minimal credit for the claimed availability. | 3/15 |
| COA Completeness | 15 | HPLC and mass spectrometry confirmed via About page and third-party sources. MZ Biolabs standard service scope applies if the lab identification from third-party sources is accurate: HPLC purity and identity confirmation, no sterility or endotoxin panels. No public COA to review for completeness. | 6/15 |
| Testing Recency | 10 | No dated COAs publicly accessible. Operation since 2013 implies ongoing testing across a 13-year catalog. No evidence of stale documentation confirmed from public sources. Moderate credit for a long-running vendor without documented recency gaps. | 4/10 |
| Policy Transparency | 5 | Shipping & Returns page publicly linked at /shipping-and-returns/. Houston, TX is mentioned in third-party records as the operating location but no address appears on the public site. GenX was named as a respondent in Eli Lilly's USITC tirzepatide trademark investigation for false designation of origin (added May 21, 2024, Inv. No. 337-TA-1377). This is a documented public record from the ITC docket. The investigation's status and resolution are factual records that affect the Policy Transparency score, as they represent a verifiable legal finding about product labeling integrity. | 1/5 |
| Operational Track Record | 5 | Est. 2013, approximately 13 years of operation - among the longest in the VTS catalog alongside PureRawz. Houston, TX identified as operating location in third-party records. A 13-year operational history is a meaningful signal in a market where vendors appear and close within months. The USITC enforcement context (named respondent for false designation of origin) offsets the track record credit and limits this score from the maximum. | 3/5 |
| Total | 35/100 |
