Tag: Mass gainer storage

According to researchers, protein powders can have a shelf life of up to 1.5 years when stored under ideal conditions. However, a critical question for many users is: can we store mass gainers in the fridge once the container is opened or the shake is mixed? The answer depends entirely on whether the product is in its dry, powdered form or already mixed with liquid.

Over 75% of mass gainer users are unsure about how long their supplement will last, citing confusion over serving sizes and expiration dates. The duration of a mass gainer depends on several factors, including the container size, your dosage, and how consistently you use it. This guide will clear up the confusion and help you get the most out of your purchase.

While protein powder supplements, including mass gainers, are typically low-moisture products with a long shelf life, improper storage can cause them to spoil before the expiration date. Knowing how to know if a mass gainer has gone bad is essential for ensuring your safety and getting the most out of your investment in your fitness journey.
