FAQ

6. How should I store ROCKJAW? Please store in a cool, dry place. The gum is susceptible to melting in hot and humid conditions. We are not responsible for heat damaged units.

8. Why not just chew regular gum? Yes, chewing gum can make a difference - but small. Regular gum is not designed to give you a jawline - otherwise everyone that chews gum would have a sharp, chiseled jawline right now. ROCKJAW is 10X stronger than regular gum - made to help hypertrophy of the masseter muscles in your jaw. 

9. How long should I chew it for? ROCKJAW must not be chewed for more than 1 hour a day unless advised. The optimal time for beginners is between 10-30 minutes.

10. I'm on a liquid diet - will this help to strengthen my jaw? Yes! ROCKJAW can also help to regain jaw strength.

11. My gum has melted, what can I do? Providing that you stored it correctly, the gum shouldn't melt. If melted, place it in the refrigerator for an hour to regain strength. Please follow our storage instructions - we are not liable for damages.

12. Does ROCKJAW affect TMJ? ROCKJAW can be used only if used with precaution. If you suffer from TMJ, do not chew larger pieces and ONLY chew for 5-10 minutes a day. Please consult with an orthodontist for confirmation before starting your training program with ROCKJAW.
