We offer damage protection on every order. If your product arrives damaged in transit, contact us with photos for a one-time replacement. All claims require photo evidence and are subject to review. One replacement per customer per order. Reconstituted products are not eligible. We do not offer refunds for change of mind or misuse.
Are your peptides third-party tested?
Yes, every batch is tested by independent, accredited U.S. laboratories for purity verification and Mass Spectrometry for identity confirmation. Test results are published on each product page as Certificates of Analysis (CoA).
How long does shipping take?
Orders are processed within 1-2 business days. Standard shipping typically arrives within 3-5 business days from fulfillment. Express and overnight options are available at checkout. Every order includes free shipment protection.
Do you ship internationally?
