Frequently Asked Questions
1. What is Third Set Aminos?
Third Set Aminos is a U.S.-based research peptide supplier specializing in high-purity compounds for laboratory and scientific use only.
Our mission is to provide researchers with verified, consistent, and transparent materials that meet the highest industry standards.
2. Are your products for human use?
No. All products sold by Third Set Aminos are strictly intended for laboratory research use only (RUO).
They are not for human consumption, medical treatment, diagnostic procedures, or veterinary applications.
Purchasing from us signifies your agreement to use all materials in compliance with these restrictions.
3. How are your products tested?
Every batch is independently verified by accredited third-party laboratories using validated analytical methods such as:
- HPLC (High-Performance Liquid Chromatography)
- Mass Spectrometry (MS)
- FTIR (Fourier-Transform Infrared Spectroscopy)
This ensures each compound meets or exceeds specifications for purity, identity, and consistency.
All test results are available as Certificates of Analysis (COAs), which can be verified by batch or order number on our website.
4. How do I access my COA (Certificate of Analysis)?
Each batch we produce is associated with a unique batch number.
You can view or download the COA by entering your order number or batch number on our COA Verification Page.
If you have any trouble locating your COA, please contact us at support@thirdsetaminos.com.
5. How should peptides be stored?
To maintain stability and potency:
- Store peptides in a cool, dry environment away from direct light and moisture.
- For long-term storage, refrigeration (2–8°C) or freezing (–20°C) is recommended.
- Always minimize freeze-thaw cycles to preserve compound integrity.
Detailed storage instructions are provided on each product page and label.
