was looking at stock levels first since we need a minimum of three vials to start the next round of assays, and they had enough in cold storage to ship immidiately — lead time is typically 3-5 business days depending on your location.
i've used their epithalon before, and the lyophilized cake was consistent batch to batch, which matters when you're reconstituting for cell work — the white powder rehydrates cleanly in water or buffer with no visible residue.
the purity is stated at ≥99% verified by HPLC and MS, but what i actually care about is the endotoxin level under 0.1 EU/mg since we're running sensitive metabolic assays, and the COA they provide batch-specific documentation for each lot.
it's sterile filtered and packed under inert gas, which means less risk of degradation during shippng even if the cold chain has a minor hiccup — storage is -20°C or below for full 24-month shelf life.
they list compound-specific molecular weights and CAS numbers on request, which is standerd, but i'd verify the sequence by mass spec if you're working with retatrutide or cagrilintide — better to be sure than assume.
also, this isn't for in vivo work with large animals given the small research quantities avaliable, so if you need gram-scale orders, you'll want to check MOQ with the suplier first.
