What is the shelf life of Peri Rx? I’ve had other pre-workouts harden even when unopened in the past, so I’m wondering if I were to buy a bulk of a few Peri Rx products, would they last until I use them? Example, if I bought six, would the last one last until the sixth month?

There’s likely to be some clumping with most multi-ingredient supplements over ~12 to 18 months unless stored in a climate controlled facility. There’s no shelf-life per se’ regarding degradation of materials, but we don’t recommend using product after about a year to reduce the risk of clumping.
