Whey is one of the most popular protein powders on the market, especially among bodybuilders and people who regularly do resistance workouts. When a protein is absorbed fast, the body can immediately begin its muscle repair and rebuilding process.

No rocket science here. Start with checking the looks of the powder and how does it smell. If any moisture got into the powder, there would be wet clumps or even mold, and that means you should throw it away.

The cooler temperature will slow the rate at which the contents start turning. To summarize, the best time to drink a protein shake from a workout perspective is widely believed to be minutes after exercise.
