What “Research Use Only” Means
“Research use only” (often shortened to RUO) is a label that says a product is sold for laboratory research. It is not approved, cleared or intended for use in people or animals, and it is not sold to diagnose, treat or prevent anything.
Where the label comes from
The phrase is best known from US FDA labeling rules for lab products. For in vitro diagnostic products in the research phase, the required statement is “For Research Use Only. Not for use in diagnostic procedures.” (21 CFR 809.10(c)(2)(i)). Research chemical and peptide suppliers use the same idea: the product is a research material, not a medicine.
What the RUO label does not mean
- It is not FDA approval, and it is not a quality grade.
- It does not tell you the product’s identity or purity. Only a lab report can.
- It does not make any use outside a laboratory acceptable.
How to check a research-use-only peptide before you buy
- 1Find the batch lab report (COA). It should name the testing lab, the batch or lot, the test date and the method.
- 2Check identity and purity separately. HPLC measures purity. Mass spectrometry (MS) confirms the molecule is what the label says. HPLC-MS covers both.
- 3Match the batch. The report should match the batch you receive, not a generic sample.
- 4Look for a way to verify it. Can you confirm the report with the lab, or have the vial tested yourself?
- 5Check storage and handling. Lyophilized (freeze-dried) peptides are typically stored frozen at around -20°C.
How Wasatch Peptide handles research use
- Every order requires an account and a research-use attestation, and buyers must be 21 or older.
- We publish batch HPLC-MS identity and purity reports in our COA library.
- You can send any vial you bought from us to an independent lab, and we credit the full vial price back whatever the result.
- We don’t publish dosing or use instructions, and we don’t host product reviews describing personal use.
For laboratory research use only. Not for human or veterinary use.
