Is Core Med Science third party tested?
Yes, for every product we track. Of the 6 Core Med Science products we track across 6 categories, 6 have their exact package named by a certifier.
A certifier lists specific packages against each certificate, not a whole brand. So “Core Med Science is third party tested” can be true of one bag while the size, strength or form beside it has no listing. Each row below says which.

No listing is an absence in a database, not a failed test: most supplements have never been independently tested. NSF Certified for Sport, the Informed programs' published product lists, the IFOS directory and USP's directory are each read in full. Each product page names the day.
Every category we compare: the home page. Every question we answer: the question index.
What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
