Perfect transaction. This is research is important to me and i researched several companies before settling on Chemyo. I kept seeing Chemyo on the top of lists for most reliable sources. I won’t be going anywhere else for future purchases.

Frequently asked
questions

Identity, purity, and concentration cannot be confirmed by appearance. They must be verified through analytical testing. Every released Chemyo batch is tested by independent laboratories before it is offered for sale. All products must pass identity and purity testing, and for solution products the finished liquid is also tested to confirm the actual mg/mL against the label claim. A batch that does not meet the release criteria is not sold.

Every released batch must have confirmed compound identity and raw material purity of 99% or higher. For solution products, the finished liquid must also test within 10% of the labeled mg/mL. A batch that fails any required checkpoint is not released. The full process is documented at chemyo.com/testing.

Raw material testing confirms the compound is correct and highly pure before production begins. For a solution, that alone does not confirm the concentration inside the bottle. So finished bottles are tested by an independent laboratory using HPLC to verify the final mg/mL, not only the starting material.

Testing a single bottle only confirms that one unit. To confirm the entire batch was mixed and filled consistently, our third-party fulfillment center randomly selects multiple finished bottles from the same inventory that ships to customers and sends them for independent HPLC concentration testing. The number of samples scales with batch size, and all must meet specification before the batch is released.

In practice, no. Our release process only permits a batch to ship once it has met the same standard: 99% or higher raw material purity and, for solution products, concentration within 10% of the label claim. Because every batch in circulation has cleared that identical bar, the batch you receive does not change the content or the quality.
