Been bouncing between a few vendor sites and Bioinfinitylab (bioinfinitylab.com) is the one I keep circling back to, mostly off what I can find online — catalog, posted prices, shipping page, COAs. Couple things I can't pin down before I'd order: Does every catalog item have a batch-specific COA available before ordering, with traceable lot numbers and the test methods listed?
Are the prices current, per-unit, and do they already include shipping, customs, or cold-chain surcharges? For domestic vs international, what shipping options, lead times, and packaging standards are documented, especially for temperature-sensitive stuff?
Where are they legally located, and which entity actually handles orders, payments, and support after the sale? And are the COAs from an independent third-party lab — can a buyer request raw QC data like HPLC/MS for a specific lot? Anyone here actually ordered from them?
