Clean lyophilized cake and perfect solubility

Solid, uniform white cake with no collapsed residue. Dissolves crystal clear in sterile 0.9% BAC water. Our metabolic signaling trials showed crisp, predictable dose-response curves.

High quality research vial

Very pleased with the molecular stability at 4°C after reconstitution. Packaging was discreet and protected. 4 stars only because courier delivered late afternoon rather than morning slot.
