Trying to decide between 24Peptides and another supplier for lab stuff, and I keep going back and forth. Does every catalog listing have a lot-specific COA—HPLC/MS, date, batch number—available before you buy, or are only representative COAs posted?
Are those COAs from an independent third-party lab, and can you actually verify the testing lab and methods? What are the shipping terms: origin location, carrier, estimated transit, packaging/temperature control, and tracking?
Are prices listed per vial/gram with clear purity, quantity, and batch-specific pricing, or do they change by lot/order size? And is there a verifiable business address/contact plus a return/replacement policy if a shipment is delayed, seized, or arrives compromised?
If anyone has dealt with them, I’d love the real version.
