Frequently Asked

Clear answers about our peptides.

Everything you need to know about quality standards, testing, and ordering.

How pure are your peptides?
Our peptides are independently tested to verify purity, identity, and consistency on every batch. Each lot receives a Certificate of Analysis so results are traceable to the exact vial you receive.
When will my order ship?
Orders are processed quickly and typically ship within 1–3 business days. All orders ship domestically from within the United States; delivery time varies by destination.
Are these for human consumption?
No. All Star Aminos products are sold as laboratory research peptides for research use only. They are not intended for human or animal consumption, and not intended to diagnose, treat, cure, or prevent any disease.
Do you provide Certificates of Analysis?
Yes. Every batch ships with a COA, and each vial carries a QR code linking directly to its batch-specific documentation.
