Additional Information

Heavy lifting puts extreme stress on your muscles and joints, which is why it's essential to provide your body with the firepower it needs to come back bigger and stronger.

If you take a protein supplement every day to build your muscles, make sure to stack it with Super Joint Guard to help support your cartilage - so you can unleash the pain on the weights, not on your joints.

Store at room temperature and avoid excessive heat.

Individual results may vary.
