"Shipped out same day. Box was padded well and nothing shifted around in transit."
"Labels are clean and easy to read, matches the photos on the listing exactly."

This research kit contains ten individually sealed vials of 10iu lyophilized material, supplied for in-vitro laboratory research only.
Kits are supplied as a complete box so laboratories running longer protocol series can work from a single lot rather than mixing lots between experiments.
Each lot is submitted for independent identity and purity analysis before release, and lot-specific documentation is available on request.
