Purity is the product.

Apollo Peptides supplies high-purity peptides and research materials to laboratories, universities, and independent researchers across the United States. Our standard is simple: every product is analyzed, every batch is documented, and nothing ships until it meets spec.

Our standard

We hold our catalog to a target purity of 99% or higher, verified by independent third-party laboratories using HPLC and mass spectrometry. A certificate of analysis (COA) is available on request for the materials we carry, so you always know exactly what you’re working with.

Why researchers choose us

• Verified purity. Third-party tested and batch-documented — not just a number on a label.
• Reliable supply. Consistent stock and careful, cold-chain-aware handling.
• Fast, discreet shipping. Next-business-day dispatch before cutoff, in plain packaging.
• Real support. Questions about handling, storage, or your order get a real answer.

Responsible by design

Everything we sell is intended strictly for laboratory and research use. We do not provide dosing guidance, medical advice, or therapeutic claims of any kind, and we expect our materials to be handled by qualified individuals in an appropriate research setting.
