About StarRUO

We source it. verify it, and finish it.

StarRUO is a peptide finishing and analytical facility in Phoenix, Arizona. We source raw peptide material from vetted, audited suppliers, then verify, test, lyophilize, fill, seal, and ship every vial in-house. From incoming lot to finished vial, every critical step is completed under one roof in our Phoenix facility.

// No Middlemen. No Mystery.

Our Mission

The research peptide market has a problem: most of what’s sold online is white-labeled. A reseller buys bulk from a supplier, applies their own label, builds a glossy website, and charges 2–4× what the actual finishing lab charges. The researcher pays the markup. The lab doing the actual work gets cut out of the conversation entirely.

StarRUO exists to remove every layer between the lab and the research customer. We source raw peptide material from audited suppliers and verify every incoming lot in our analytical lab before it reaches production. From there, we test it, lyophilize it, fill it, seal it, and ship it — all from our facility in Phoenix. No middlemen. No drop-shipping. No mystery about where your vial came from.

What Sets Us Apart

01

In-House Finishing

We perform every critical finishing step in-house. Every incoming lot is verified in our analytical lab before processing. From raw material to finished vial, every batch is tested, lyophilized, filled, sealed, labeled, and prepared for shipment in our Phoenix facility — using our own lyophilizers, fill rooms, and analytical equipment. Finished in Phoenix, AZ — every vial.

02

In-House Analytical Lab

Every incoming lot and every finished batch is tested in our in‑house analytical lab before shipment using two complementary techniques: HPLC for purity verification and Mass Spectrometry for identity confirmation. HPLC measures peptide purity and detects impurities, while Mass Spec confirms molecular mass and verifies that the material matches its expected identity. Most peptide labs stop at the industry‑minimum, but we believe customers deserve more — the Certificate of Analysis you see on our product pages is generated by our instruments, not passed through from a supplier.

03

99%+ Purity — Non-Negotiable

We hold every compound to a 99%+ purity minimum. Lots that don’t meet that floor are not shipped. This is a hard rule, not a marketing claim.

04

In-House Analytical & Fill Facility

Our Phoenix facility operates under documented internal standard operating procedures. Quality control testing, lyophilization, vial filling, packaging, and fulfillment all happen on-site.

05

Direct Pricing

Because every vial is finished, tested, and packaged in-house, we eliminate every unnecessary layer of markup. You pay direct pricing — not reseller pricing — for the same verified material and the same Certificate of Analysis.
