Are these products for human use?
No. Every product is sold strictly for laboratory research and is not for human or animal consumption, diagnosis, treatment, or any therapeutic use. By ordering you confirm you are a qualified researcher using these materials for research purposes.

What if a vial arrives damaged?
If a vial arrives damaged or the order is incorrect, contact us and we’ll arrange a reshipment or refund for the affected item.
How should the materials be stored?
