Research Peptides
Shipped To Seattle
From the Fred Hutch cancer research campus to Amazon's biotech investments, Seattle is one of the most sophisticated peptide markets in the US. BioInfinity Lab supplies ≥99% purity peptides with rigorous documentation.
Why Seattle
Fred Hutch, UW Medicine, and the Pacific Northwest biotech corridor.
Seattle houses one of the country's most rigorous biomedical research communities — Fred Hutchinson Cancer Center, UW Medicine, Allen Institute for Brain Science, and dozens of startups spun out of the Bezos-era biotech investments. Peptide buyers here demand third-party COA verification for every purchase, and that's exactly what we ship: HPLC + mass-spec results traceable to the lot number printed on the vial. UPS Ground from Manhattan reaches Seattle metro in 4 business days, with 2nd Day Air available for time-sensitive protocols.

Seattle FAQ
Questions, before you order.
How fast is peptide shipping to Seattle?+
UPS Ground from our Manhattan facility reaches Seattle-area ZIPs in 4 business days. UPS 2nd Day Air is available at checkout for expedited protocols.
Do you ship to Fred Hutch or UW Medicine researchers?+
Yes. We regularly ship research peptides to Fred Hutchinson Cancer Center, UW Medicine, and the Allen Institute programs. Institutional POs on Net-30 terms are supported for qualified accounts.
Which peptides are most requested in the Pacific Northwest?+
Seattle-area researchers most often order MOTS-c and Thymosin Alpha-1 (immunology), BPC-157 and TB-500 (tissue repair), and Epithalon (telomere and longevity research).
How should I store peptides in Seattle's humid climate?+
Humidity primarily matters for lyophilized (dry) peptides. Keep unopened vials at –20°C freezer temperature until reconstitution. Once reconstituted with bacteriostatic water, refrigerate at 2–8°C and use within the peptide's post-reconstitution shelf life (typically 4 weeks).
