Before I commit money to Blackline Scientific (blacklinescientific.com), here's what I'm trying to sort out from public listings. The catalog shows four products — can anyone confirm the exact product name, form, quantity, and purity grade for each, and whether those four are the full current catalog?
Are the COAs batch-specific and available before purchase?
Do they name the third-party labs, analytical methods, and lot numbers matching what actually ships? Prices: listed per unit and in USD?
Do they include shipping, taxes, or handling? Any minimums or bulk pricing? Shipping origins, lead times, packaging, tracking — US-only or international?
And where in the US are they based/fulfilled from?
Is there a registered business address or any verification for the entity?
