All sales are final

All sales are final. Due to the nature of our products and inventory, we are unable to accept returns or issue refunds once an order has been placed. Research compounds cannot be restocked or resold once they leave our facility, as their integrity and handling can no longer be guaranteed.

Quality assurance

Product quality is independently assessed by third-party laboratory testing for identity and purity. Results are published on each product page and on our Lab Results page. By completing a purchase on this website, you acknowledge and accept the third-party testing provided for each product.
