We don’t ship with ice. Lyophilized peptides are shelf-stable at room temperature for weeks — sending unnecessary refrigeration is theater. We’d rather invest in purity testing than gel packs.

Policy update as of 2026-07-15: Luminos previously shipped some products with insulated packaging and cold packs. We’ve reviewed the stability data on lyophilized peptides and confirmed that room-temperature transit within Priority Mail windows does not degrade product integrity. Cold packs are no longer included by default. Reconstituted product should still be refrigerated at 2–8°C.

Packaging & Handling

• All orders ship in plain, unmarked packaging with no external branding
• Padded protective mailers. Lyophilized peptides are shelf-stable during shipping; no refrigeration required in transit. Store at −20°C long-term; refrigerate after reconstitution
• Each order includes a lot-specific Certificate of Analysis (COA)
• Free Solution included with every order

Shipping Coverage

We currently ship to all 50 U.S. states. International shipping is not available at this time. We do not ship to P.O. Boxes for expedited or overnight orders.

Order Tracking

A shipping confirmation email with tracking information is sent once your order has been dispatched. You can also track your order status through your account dashboard.
