Yes. Every batch is supported by a COA confirming identity, purity, and analytical verification.
Transparency is a core part of our quality process.
---
3. Do you test products in‑house? 🧪
Each batch is verified through a combination of supplier documentation and independent third‑party testing.
New batches undergo rolling COA verification to maintain long‑term consistency.
---
4. Why do COA results vary slightly? ⚖️
Minor variations are normal due to differences in sample prep, equipment calibration, and environmental conditions.
All results remain within research‑grade standards.
---
5. What is RUO? 🔬
RUO (Research Use Only) means products are intended strictly for laboratory research, assay development, and scientific investigation.
They are not approved for human or veterinary use.

11. How should I store peptides? ❄️
For research stability:
• Store long‑term at –20°C
• Store short‑term at 4°C
• Keep vials sealed, dry, and protected from light
• Avoid repeated freeze–thaw cycles

13. Do you include solvents?
Not by default.
Solvents and reagents are available in our Reagents & Solvents section.

15. Do customers ever run their own third‑party testing? 🧬
Some long‑standing researchers independently verify batches through accredited labs.
When they choose to share those COAs with us (with batch number + RISYNTH BIO listed), it contributes to community transparency.
In select cases, we may extend a courtesy store credit as appreciation.
