"Third-party tested" is a claim about who tested it. A certificate you can open is a document. Only the second is counted here.
1 × 5000mg from Eliteedgebiotech gets you 5000mg for $25.00 — saving $3.00 against the cheapest 600mg at $28.00.
You end up with 4400mg more than you asked for. See the listing →
