According to a Premier Protein executive, the dry nature of protein powders means there is little risk of bacterial growth, but this does not make them invincible to spoilage. The short answer to 'can Premier Protein go bad?' is yes, both the powders and the ready-to-drink shakes can and will degrade over time, losing quality and potentially becoming unsafe if mishandled.

According to food safety experts, an unrefrigerated protein shake lasts only about two hours before bacteria multiply to unsafe levels. Understanding exactly **how long does a protein shake last before it goes bad** is critical for both your health and for making the most of your supplement investment.
