AVAILABLE IN 4 REFRESHING FLAVOURS.

THE UK'S NO.1 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.

We now ship to over 40 countries worldwide.

HAND-PICKED & PACKED CRYSTALS

We do it the traditional way.

Did you know it takes an average of 7 minutes to pick and pack just one ROCKJAW tin?

Each ROCKJAW tin is composed of the finest hand-picked crystals, which are then packed by hand. No process is automated.

£1 DONATED OF EVERY PURCHASE

For every order, we split the donation to support Men's Mental Health and Cardiovascular Research. All tips left by customers will also be donated to these charities.

Heart diseases are the most common cause of death, in both men and women. For every £1 or equivalent donated, we donate 50% to support research in heart diseases.

We're united against suicide. The suicide rate for men is 3.5 times higher than among women. That's why we've chosen to donate the other 50% to CALM (Campaign Against Living Miserably).
