According to research, creatine monohydrate powder is extremely stable and can last for several years, even beyond its expiration date, if stored properly. The common issue of finding your powder hard and clumpy is usually not a sign of spoilage, but rather moisture exposure. Before you decide to toss it, understand what causes the clumping and how to assess its safety.
