Ordering is account-gated. Accounts are held by qualified researchers and institutions with researcher type on file — there is no guest checkout and no anonymous ordering.

Every lot ships with a batch-specific Certificate of Analysis. The COA reports identity and purity by HPLC, mass spec confirmation, sequence, and endotoxin screening for that exact lot — not a brand-wide or representative figure.

Independent, U.S.-based third-party laboratories. We do not publish in-house results, so the figures on your COA come from a lab with no stake in the outcome.

Refrigerate upon arrival. Lyophilized and room-temperature stable. Lyophilized material is stable at -20°C for 24+ months; once reconstituted, store at 2-8°C and expect roughly ~30 days. Avoid freeze/thaw cycles and protect from light.

Yes. A retention sample from every lot is securely stored, so any batch you have bought can be re-verified against its original certificate on request.

Tracked and insured, under a controlled cold chain, in plain outer packaging with no product markings on the exterior.

Yes. Purchase orders, formal quotes, and net terms are available for universities, CROs, and commercial laboratories. Institutional purchasing is handled through your account.
