I think JAW-151 was referring to the difference between lower quality Chinese creatine to well-known ones such as Creapure. From bb.com:

Just as there is a difference between $100 champagne and $15 dollar champagne, there's a difference between high-quality creatine and inferior-grade creatine. Traditionally, Chinese creatine is a lower quality product, with more contaminants such as creatinine, sodium, dicyandiamide, and dihydrotriazine. German creatine, from companies such as SKW (Creapureâ„¢), are cleaner, purer products.
