Returns & Quality Guarantee
Every product is HPLC and Mass Spec tested to ensure 99%+ purity
Our Commitment to Quality
At Acme Peptides, we stand behind every product we sell. All peptides undergo rigorous third-party testing using both HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry to verify identity and purity before they reach our customers.
Every order ships with a Certificate of Analysis (COA) from an independent laboratory. If any product fails to meet our published purity standards, we will replace it at no charge.
What's Covered
Product Doesn't Meet Purity Specs
If independent testing shows purity below our published specifications, we will send a free replacement or issue a full refund.
Damaged in Transit
If your order arrives damaged or with broken seals, contact us within 7 days with photos for a free replacement.
Wrong Item Received
If you receive an incorrect product, we will ship the correct item immediately at no additional cost.
Return Window
Returns and replacement requests must be submitted within 30 days of the delivery date. Products must be in their original, unopened packaging unless the claim relates to purity or identity concerns.
