All products have undergone third-party analytical testing through Janoshik. Copies of the available Certificates of Analysis (COAs) can be provided upon request.

Certain identifying details on these reports have been blurred to protect confidential supplier and sourcing information. However, enough information remains visible to demonstrate that the manufacturer and client identifiers are consistent across the COAs provided.

Developing a dependable supply relationship has required years of evaluation and thousands of dollars in sourcing and independent testing. Access to a consistent source with an established testing history is part of the value we provide for our customers.

COAs are useful analytical records, but they have limitations. A COA should not be interpreted as an absolute guarantee regarding every vial or batch. The only way for a purchaser to independently confirm the identity, purity, and contents of a specific product is to submit a sample from that product or batch directly to a qualified laboratory for testing.

Given the nature of wholesale distribution, purchasers are encouraged to conduct independent third-party testing.

Regardless of any Certificate of Analysis (COA) provided by a supplier, independent testing is the most reliable way to verify a product’s identity, purity, and quality.

We stand behind the quality of our research products. If a product is independently tested by Janoshik and does not meet the stated specifications, we will refund the purchase price of the affected batch. This refund applies only to the product and batch tested—not to other products included in the same order.

If you intend to submit a vial for third-party testing, please notify us before placing your order. We will provide a specially identified vial so we can verify that the test results correspond to the product and batch supplied by us. Refund eligibility is subject to verification of the laboratory report, vial identification, and batch information.
