About StarRUO

Every compound we ship is verified at 99%+ purity by HPLC. This is a hard minimum — batches that don’t meet that floor are not sold. Mass Spectrometry confirms identity on every batch.

Every batch is tested in our in-house analytical lab using three complementary techniques. We use High-Performance Liquid Chromatography (HPLC) for purity quantification, and Mass Spectrometry for molecular weight / identity confirmation. The Certificate of Analysis on each product page is generated by our instruments.

A COA is a document confirming the identity, purity, and other quality attributes of a peptide as verified by laboratory testing. At StarRUO, every product has a COA available on its product page, generated from our in-house HPLC and Mass Spectrometry testing before shipment.

Applicable materials undergo endotoxin and sterility testing in addition to HPLC, and Mass Spectrometry. Results are documented on the Certificate of Analysis.

It is discarded. We do not lower the purity standard, blend lower-purity material into shipping inventory, or sell off-spec compound at a discount.

Quality, Purity & Testing

StarRUO is a quality-controlled analytical facility based in Phoenix, Arizona. We source raw peptide material from audited suppliers and perform verification, lyophilization, filling, and packaging in-house — we are not a reseller or white-label brand. We supply qualified researchers, biotech companies, and academic institutions directly.

No. Many peptide brands purchase finished peptides from manufacturers like us, apply their own label, and resell at a 2–4× markup. StarRUO sells direct from the lab that synthesized the compound. Same product, no markup chain.

All products are processed, verified, lyophilized, and packaged in-house at our quality-controlled analytical facility in Phoenix, Arizona. Testing, lyophilization, and packaging all happen at the same facility under controlled conditions.

Ordering & Shipping

Orders are processed within 24 hours. Orders placed and paid before 12 PM MST typically ship the same business day from Phoenix, AZ. Tracking is provided on all shipments.

Yes — orders of $200 or more ship free within the United States. Orders below that amount ship at a flat rate.

We currently ship within the United States only.

Secure, protective packaging with research-use labeling. Cold-pack options are available for temperature-sensitive compounds. Tracking is provided.

We accept major credit cards and select alternative payment methods. Payment options are shown at checkout.

Orders can be modified or cancelled before they enter the fulfillment process (typically within 1–2 hours of placement). Contact orders@starruo.com immediately.

Products & Storage

All peptides are shipped as lyophilized (freeze-dried) powder in sealed sterile vials. Lyophilized form preserves stability during shipping and long-term storage.

Lyophilized (unreconstituted) peptides: -20°C for long-term storage; 2-8°C for short-term storage (up to a few weeks). Solutions prepared for in-vitro laboratory work should be stored at 2-8°C and used within the timeframe defined by the applicable research protocol. Avoid repeated freeze-thaw cycles.

Yes. COAs are posted on every product page. You can also email orders@starruo.com to request a specific batch COA.

Compliance & Legal

No. All products are sold strictly for laboratory and research purposes only. They are not intended for human consumption, veterinary use, or any medical treatment. By purchasing, you confirm you are a qualified researcher complying with all applicable local and federal laws.

No. The products sold on this site are research chemicals and have not been evaluated or approved by the FDA. They are not drugs and are not intended to diagnose, treat, cure, or prevent any disease.

No. StarRUO is a chemical supplier. We are not a compounding pharmacy or chemical compounding facility as defined under Section 503A of the Federal Food, Drug, and Cosmetic Act. We are not an outsourcing facility as defined under Section 503B of the Federal Food, Drug, and Cosmetic Act.

Purchasers must be 21 years of age or older and qualified researchers, laboratory professionals, or institutions purchasing these compounds strictly for in vitro research use.

Institutional & Bulk Research Inquiries

Yes. Qualified institutional research accounts and volume research customers can contact support to discuss documentation requirements and lead times for larger orders.

As an analytical synthesis facility, we accept custom reference-material requests subject to feasibility, quantity, and compliance review. Contact support with your specifications.
