Fair questions

What researchers ask before their first order.

Everyone says “99% pure.” Why trust yours? +

A purity number means nothing without a report for the exact batch.

Request the report for the specific batch. Purity alone is not proof of sterility or safety.

There are cheaper vendors. +

A cheap vial you can't verify is the most expensive one you'll buy.

Compare product identity, batch reports, quantities and order terms before choosing a supplier.

Will it be in stock when I reorder? +

Switching material mid-study ruins consistency.

Check the current strength and availability on the product page before placing each order.

How long does it take to get my order? +

Fast — orders ship by the next business day, often the same day.

Available delivery methods and prices depend on the address entered at checkout.

What if my order is wrong or damaged? +

No runaround.

Reach out and a real person will make it right.
