Frequently Asked Questions

AI
RTD shakes offer convenience but often contain more sugar or additives than powder. Powder allows you to control ingredients and is generally cheaper per serving, while RTD is ideal for on-the-go needs.
Most high-quality shakes provide between 20g and 50g of protein per serving. For post-workout recovery, aim for at least 20g. Check the label to ensure the protein source matches your dietary preferences.
Brand UFIT and Grenade often provide competitive pricing for bulk packs. Optimum Nutrition offers premium quality but at a higher cost. Compare price per gram of protein to determine the true value.
