Came across Privaini (privaini.com) while comparing suppliers — public listings show published prices, shipping info, and COA docs, so there's something to look at. But: are the COAs batch-specific and third-party, and do they list method/instrument, purity, and a lab name/contact I can verify independently?
Where does Privaini ship from, and are timelines, carriers, tracking, and packaging spelled out before checkout? How are the prices structured — currency, taxes/fees, minimum order, bulk or research-quantity discounts — and do they actually stay current?
And does every product listing link to the exact current batch COA before purchase, or are COAs provided only...
