Before I put any money toward Bloodtestscanada (bloodtestscanada.com), I'm going off what I can find online: their listed catalog, published prices, shipping info, and COA docs. Stuff I'd want sorted out first: Does the catalog actually list purity, form, quantity, and lot-specific identifiers per item, or do you have to ask?
Are COAs tied to each batch/lot, and do they show the third-party lab name, methods, spectra, and test dates? Shipping: stated origin, where they'll send, which carrier, how it's packaged, and what they do for temperature-sensitive items.
Prices: CAD or something else? Taxes and fees in or out? Any bulk or testing-order terms spelled out?
And can they confirm location/jurisdiction, plus whether the COA and shipping claims are independently verifiable?
