THE WORLD'S NO.1 MASTIC JAWLINE GUM

Biology proves that tension must be placed in order for a muscle to grow - a process known as 'hypertrophy'.

Our mission was to create a product that exhausts and builds the masseter muscles (which are responsible for giving your jaw it's sharp structure) in the same manner as training your biceps.

Within 6 months, ROCKJAW became the UK's NO.1 BEST-SELLING jawline gum with a 4.8 Star customer rating.

Now, we're the BESTSELLING mastic gum in USA, Australia and Canada and ship to over 40 countries worldwide.

FAQs

DOES ROCKJAW CAUSE/AFFECT TMJ? 🔪

No, ROCKJAW can be 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 a dental professional before starting your training program with ROCKJAW.

WHY IS ROCKJAW SO EXPENSIVE? 💰

Mastic gum is very expensive, see the cultivation process here: https://www.youtube.com/watch?v=F95jAZtVmFE

Separating good quality mastic that ends up in your tin is a labourious process, taking several hours.

Then, each ROCKJAW unit takes approx. 7 minutes to pack and process!

HOW DO I STORE ROCKJAW❓

Please store in a cool, dry place. Mastic is highly susceptible to melting in hot and humid conditions. We are not responsible for heat damaged units.

CAN I RE-USE MY GUM? 🤔

Yes! Mastic gum is 100% reusable. We also stock Storage Tins to help you re-use your gum!
