Quality & Verification
At Poly Biotech, quality is not a marketing claim – it is a process.
Every product we distribute is selected, handled, and verified with the expectation that it will be used in professional, clinical, or research environments where consistency and reliability matter. Our quality framework is built around supplier vetting, batch traceability, and independent third-party verification.
This page outlines how Poly Biotech approaches product quality and provides access to available Certificates of Analysis (COAs) for verified batches.
Independent Third-Party Testing
Where applicable, Poly Biotech works with independent analytical laboratories to confirm key quality attributes such as:
- Product identity
- Purity and composition
- Batch consistency
Certificates of Analysis are generated by external labs and reflect results for a specific production batch, not a generalized product claim. As with any analytical testing, results apply only to the tested sample and batch referenced in the report.
Certificates of Analysis (COAs)
Below you will find Certificates of Analysis for select Poly Biotech products and batches. These documents are provided to support internal quality control, professional review, and supplier evaluation.
Each COA typically includes:
- Product name and batch identifier
- Testing methodology used by the laboratory
- Analytical results and conclusions
Availability of COAs varies by product, batch, and testing cycle. Not all products or batches are listed at all times.
COA Library
COA Library
Each batch is independently tested for identity and purity by a third-party analytical lab.
Note: Some compounds, depending on their structure and formulation profile, may naturally present with lower assay percentages without indicating reduced quality or purity.

Bacteriostatic Water (BAC Water) – Quality Testing
In addition to identity and purity verification for select products, Poly Biotech performs analytical testing on Bacteriostatic Water (BAC Water) to confirm critical quality parameters.
| Product | Test Parameter | Result | Specification | Report |
|---|---|---|---|---|
| BAC Water | pH | 6.130 | Reference range: 6.5 – 9.0 | View PDF |
| BAC Water | Endotoxin (LAL Test) | < 0.25 UE/mL | Limit: < 0.25 UE/mL (USP Gel Clot Method) | View PDF |
Endotoxin testing is performed using the Limulus Amebocyte Lysate (LAL) method to detect bacterial endotoxins. Results apply only to the tested batch and are published for transparency and quality verification purposes.
Batch-Level Verification, Not Marketing Claims
Poly Biotech does not treat COAs as promotional material. Testing is performed to validate supplier consistency, support professional evaluation, and maintain internal quality standards.
Results are published in a structured, batch-specific format so partners can quickly locate what they need without unnecessary interpretation or noise.
Laboratory Selection & Quality Controls
Our sourcing and verification process includes:
- Supplier screening and ongoing evaluation
- Batch tracking and internal documentation
- Controlled handling and storage practices
- Purity and Endotoxin testing
- Periodic third-party verification
For Clinics, Professionals, and Wholesale Partners
If you are a clinic, practitioner, or wholesale partner and require additional batch documentation, historical COAs, or verification details, these may be available upon request depending on the product and batch.
Ongoing Commitment to Quality
Poly Biotech continues to expand testing coverage and documentation as part of an ongoing quality program. This page is updated as new batch results become available.
