Outer box gives nothing away. Inner sealed bag with desiccant + tamper-evident seal on the vial cap. Eleven orders in and nothing has ever arrived damaged or compromised.

Sturdy outer carton, sealed inner with secondary containment, tamper-evident vial caps. Premium feel without the wasteful overpackaging — about right for a reference material.

Tried to reorder PT-141 and they were temporarily out of stock — restocked within a week which is fine, but I'd suggest an email subscribe-for-restock so I'm not refreshing the page.
