Assay Supply Co. does not publish PDF certificates. Every product carries a Living COA on its own page: the record as a captioned film, with each spoken claim time-stamped, and a table that checks the film against the product record, claim by claim, with sources.
No lot test results are shown until a real lot record exists. If we can't prove it, we don't print it.
The records
- Magnesium Glycinate — Report ASC-MG
- Vitamin D3 + K2 — Report ASC-D3K2
- Creatine Hydration Powder — Report ASC-CR
- Foundational Stack — Report ASC-STK
- Foundational 60-Day Box — Report ASC-060
Watch: magnesium, at the level of the cell
One film goes deeper than the label. It follows magnesium into the cell — what it does there, claim by claim, with the same burned-in captions and sources as every product film on this site.
Magnesium Glycinate — the product record this film supports
