4 Grams, 60 sq. cm, or 120 sq. cm is required for testing.  Requirement will vary based on thickness of material

Beyond-Use Date (BUD)

LexaMed will begin by testing compounded preparations to determine the Beyond-Use Date (BUD) for a specific compounded formulation. Initial tests (time zero) are performed to establish a baseline potenc.  Testing is performed through analytical methodology at selected time intervals that is specified by the client.  Progress reports will be published at each given timepoint the client specifies.  LexaMed can store client supplied test articles as requested.


Potency testing analyzes the active pharmaceutical ingredient(s) in preparations and measures their concentrations.  Per USP Chapter <795> USP has established that the acceptable range of most compounded preparations is typically ±10%, or within the range of 90.0%– 110.0%.  Testing is completed on the preferred equipment, LexaMed’s High Pressure Liquid Chromatography (HPLC).  The HPLC is the preferred method because of its efficient and specific results.
