Felix Chemical Supply

felixchem.is · Est. 2022 · United States (Chem-LLC) · Scored August 2026

Felix Chemical Supply's entire site requires account registration to access - products, COAs, and policy pages all redirect to a login prompt. Evidence in public educational guides and community resources confirms testing via Chromate, a US-based lab, with HPLC, mass spectrometry, and endotoxin panels included from November 2025 onward. Chromate COAs include a COA number and Access Code at the bottom that allows independent verification through Chromate's own platform - but a researcher must be a customer with a COA in hand before that verification path becomes available. Pre-purchase documentation review is not possible without creating an account. The operating entity is identified as Chem-LLC in registration records. The Low band score reflects the login-gate architecture, not the underlying testing quality.

34 /100
Low
Entire site login-gated. Chromate named lab with HPLC + MS + endotoxin testing confirmed via public sources, but zero documentation accessible to unauthenticated visitors. Chem-LLC entity identifiable. Score reflects accessibility architecture, not testing quality.
Dimension Scores
DimensionMaxNotesScore
Third-Party Testing Practice 30 Chromate confirmed as testing lab based on public educational guides and community resources that reproduce Felix COA examples showing "Client: Felixchem.co" and Chromate lab headers. Testing scope documented from public COA examples: HPLC purity, mass spectrometry identity, and endotoxin testing - endotoxin added as a standard panel from November 2025. Chromate COAs include a COA number and Access Code allowing independent verification on Chromate's platform, once a COA is in hand. Partial credit reflects confirmed testing practice evidenced in public sources. Login requirement prevents public verification from the vendor's own site. 14/30
Batch Traceability & Verification 20 Batch ID format confirmed from public COA examples (e.g., 022825-AOD5 format). The Chromate COA number and Access Code shown on COA documents provide an independent verification path. This verification is post-purchase only - a researcher without a COA cannot use it. Credit for the confirmed batch-specific structure; significant deduction for zero pre-purchase public accessibility. 7/20
COA Accessibility 15 The entire felixchem.is site routes unauthenticated visitors to a login/registration page. No COAs, no product documentation, and no supporting materials are accessible without account creation. This is more restrictive than email-on-request: it requires registration before any documentation can be reviewed. Under VTS methodology, login-gated documentation scores zero on accessibility. 0/15
COA Completeness 15 HPLC, mass spectrometry, and endotoxin testing confirmed from public COA examples. Endotoxin is a meaningful differentiator - most vendors in this catalog at this price point do not include endotoxin panels as standard. The AOD-9604 COA example shows 99.431% purity and 9.507mg content. Scope credit applied based on publicly available COA fragments; full credit not possible as the full documentation set cannot be reviewed without login. 7/15
Testing Recency 10 COA example dated February 2025 (batch 022825-AOD5) confirms testing within the past year. Endotoxin added November 2025 confirms active methodology updates. Cannot verify the full current testing cadence without account access. Moderate credit for confirmed recent testing visible in public sources. 2/10
Policy Transparency 5 Policy pages are login-gated and cannot be reviewed. No physical address or phone number publicly listed on the site. Chem-LLC is identifiable as the operating entity through registration records. No individuals named. The operating entity disclosure is a partial credit relative to fully anonymous operators. 1/5
Operational Track Record 5 Est. 2022, approximately 4 years of operation. One of the longer track records in this scoring batch. US-based, domestic-only shipping confirmed from public sources. Chem-LLC entity identifiable. Credit for operational maturity relative to newer vendors. 3/5

Community Signal
Independent Test Results
A public COA example for AOD-9604 (batch 022825-AOD5) shows 99.431% purity via Chromate, with an independently verifiable COA number. This is a single documented example from a public educational resource, not a community-submitted test. Chromate COA number and Access Code allow independent verification through Chromate's platform.
Community Experience
Peptide Critic documents a 4.5/5 community rating from a small number of reviews. Community feedback from sources that have accessed the site notes endotoxin testing as a meaningful differentiator and describes fast fulfillment. The small review volume limits characterization of patterns.
Scoring Notes
Endotoxin testing is a genuine differentiator
Most vendors in this catalog do not include endotoxin testing in their standard panel. Felix Chemical Supply added endotoxin as a standard offering from November 2025. If this documentation were publicly accessible, the testing scope dimension score would be materially higher. The Login-gate is what limits the overall score, not the underlying testing quality.
The Chromate verification path is post-purchase only
Chromate COAs include a COA number and Access Code at the bottom of each document, allowing researchers to independently verify the result through Chromate's own platform. This is a meaningful verification mechanism - but it requires being a customer first. A researcher evaluating this vendor before purchase has no access to any COA, and therefore no way to use the Chromate verification path before making a buying decision.
