Anyone else poke at Avant (avant.bio) yet? I've been scrolling their catalog before spending anything and there's a lot I'd want cleared up first.
Does the catalog actually separate research-grade from other grades, and does every product list specs like purity, form, and concentration? Are the COAs batch-specific and reachable before checkout, with HPLC or LC-MS method details, the lab's name, and lot numbers that actually match what you're buying?
Also, where do they ship from, what carrier and transit window are you realistically looking at, and do they disclose packaging and temperature controls for sensitive items? The money side: are listed prices all-in with taxes, duties, shipping, or not? And do they offer bulk or institutional quotes?
Biggest one for me — if a COA result doesn't match the listed specs, then what? Reshipment, refund, stability data? I haven't found clear answers on any of it.
