Frequently Asked Questions
What makes Peptide Authority peptides different from others on the market?
Peptide Authority peptides are manufactured in the United States and held to exceptionally high quality standards, with purity exceeding 99%. All products are produced under cGMP- and ISO-aligned quality management systems and undergo rigorous third-party testing, including quantitative purity analysis, endotoxin testing (≤ 0.5 EU/mL), sterility screening, dosage verification, and stability testing.
To preserve integrity, peptides remain in −20°C cold-chain storage until shipment and are dispatched using expedited methods to ensure optimal stability upon arrival. Our formulations are designed by a cross-disciplinary team with expertise in pharmaceutical R&D, biochemistry, and regulatory compliance—because serious research demands uncompromising standards.
Are Peptide Authority peptides suitable for clinical or human use?
No. All Peptide Authority products are strictly for research purposes only.
They are not intended for human or veterinary use, clinical trials, diagnostic procedures, or therapeutic applications of any kind.
Do you provide Certificates of Analysis (COAs)?
Yes. Every batch is supported by a batch-specific Certificate of Analysis (COA), providing transparency into purity, identity, and quality testing results. COAs are available to ensure researchers can verify product integrity and consistency.
How are Peptide Authority peptides tested for quality and safety?
Each batch undergoes comprehensive quality control, including:
- Quantitative purity testing
- Endotoxin testing (≤ 0.5 EU/mL)
- Sterility and microorganism screening
- Dosage verification
- Stability testing
All testing is performed using validated analytical methods and reviewed prior to release.
How should I store my peptides upon arrival?
- Lyophilized peptides:
Store at −20°C for long-term storage. Short-term storage at 2–8°C is acceptable. - Reconstituted peptides:
Store at 2–8°C, protected from light. Avoid repeated freeze–thaw cycles to maintain stability.
How quickly are orders processed and shipped?
