FAQ
Frequently Asked Questions
Answers to the most common questions about our products, ordering, and compliance.
Every compound is synthesized and verified to 99%+ purity. Our average purity across the catalog is 99.8%, confirmed by HPLC and mass spectrometry on each lot.
Yes. Every shipment includes a Certificate of Analysis documenting purity, molecular mass, appearance, and lot number. You can also request a sample COA before purchasing.
Our products are sold exclusively for in-vitro laboratory research. They are not evaluated by the FDA and are not intended for human consumption, diagnosis, or treatment.
Peptides are produced via solid-phase peptide synthesis (SPPS) under controlled laboratory conditions, then purified and lyophilized for stability.
Orders are processed within 1–2 business days. You will receive a tracking number by email once your order dispatches.
No ship to most destinations. International orders are subject to customs clearance, which may affect delivery times. The purchaser is responsible for complying with local import regulations.
Yes. All shipments are fully insured against loss or damage in transit at no additional cost.
Contact us within 48 hours of delivery with photos and we will arrange a replacement or refund at no cost to you.
