A peptide supplier for Ann Arbor laboratories

How this material is classified

Everything in the catalogue is supplied as a research reference standard for in-vitro laboratory use. Nothing on this page is a promise about outcomes; it describes handling, documentation and logistics for Ann Arbor, United States. We answer messages from Ann Arbor during European working hours, and usually the same day. No item is a medicinal product, and none is offered for use in or on a person or animal. Confirming that the intended use is permitted in United States sits with the buyer, not with us.

Our documentation is written for someone who will have to defend the sourcing decision later. The buyer is the importer of record and is responsible for any state or federal research-chemical declarations that apply. Parcels are documented for inspection rather than routed to avoid it.

Getting an order to Ann Arbor

Repeat customers in Ann Arbor tend to settle on three or four compounds and stay with the same lots for consistency. Packing happens within a working day or three of the order being confirmed. Then it is 5–18 business days from the moment tracking goes active to reach Ann Arbor, measured from active tracking rather than from checkout. Material moves by a tracked delivery service; the route and carrier depend on the dispatch hub. The buyer is the importer of record and is responsible for any state or federal research-chemical declarations that apply.

A laboratory on the edge of Ann Arbor is served on the same route as one in the middle. Collection points in Chandler, Scottsdale, Reno, Glendale and Norfolk are handled identically. Our documentation is written for someone who will have to defend the sourcing decision later. Tracking goes live at dispatch. If a parcel stalls, we chase the courier rather than asking you to.

Understanding what you are buying

Keep the certificate with the batch: separating the two is the most common records problem we see. Peptides are short amino-acid chains. Everything that matters about one — identity, stability, behaviour in solution — follows from the exact sequence. Manufacturing residues — truncated sequences, deletions, solvent traces — are what the purity figure is actually measuring the absence of. The buyer is the importer of record and is responsible for any state or federal research-chemical declarations that apply. Freeze-drying is what makes room-temperature transit survivable; it also means the vial needs correct reconstitution before use.

Verification: HPLC, mass spec, batch records

Every batch goes through third-party HPLC purity analysis and mass-spec identity confirmation before it is released. Couriers serving Ann Arbor occasionally hold parcels for documentation, which is why the research-use declaration travels with every shipment. Purity sits above 99% across the catalogue, and the chromatogram is part of the certificate rather than a claim printed next to it. Most enquiries we take from Ann Arbor start with a question about paperwork rather than price, which is usually the right instinct. Documents are sent on request ahead of payment so nothing is bought sight-unseen from Ann Arbor.

Certificates are reissued on request for archive purposes. Keep the certificate with the batch: separating the two is the most common records problem we see. If a study spans locations, ask for batch matching at the quote stage rather than after dispatch. Smaller towns around Scottsdale receive the same tracked service as the main city.
