More About Thomas Labs

WHAT DOES PHARMACEUTICAL GRADE FISH ANTIBIOTICS MEAN? (USP)

"Pharmaceutical Grade is the highest quality substance used in products for humans and animals.  Products meeting this grade must be greater than 99% pure, and cannot contain binders, fillers, excipients, dyes or unknown substances."

"All Thomas Labs fish antibiotics have high potency and contain pharmaceutical grade quality ingredients.  

These products are designed for your pond, pet, or aquarium fish-- not for human consumption" (source: Thomas Labs Product Catalog)
