It's dried resin/sap picked from the mastic tree.

Our mastic gum comes directly from the Greek island Chios- where mastic gum comes from and has been chewed for over 2,500 years.

With daily chewing, it's possible to see a noticeable difference to the face and jawline in 3 weeks. 

People who have never trained their jawline have some "newbie gains" to look forward to. These can come pretty quickly.

Stick to it for 3-6 months to maximize results.

The best results are seen by chewing both with the front teeth and the molar teeth at the back.

Chewing with the front 4-8 teeth puts emphasis on the lower, outer portion of the masseter muscle on your jaw (see below).

That is the most important section for improving the jawline's appearance.

Chewing the back molar teeth puts emphasis on the entire masseter muscle and some on the temporalis muscle.

This chewing technique will exhaust the masseter muscle the fastest.

I recommend using both techniques.

Your chest will shrink if you stop benching pressing. Same with your Masseter muscles. Though I find they lose muscle much slower than other parts of the body.

Either way, you can't stop working them out for a year and expect them to stay the same size.


Does bench press work? Do squats work? Your Masseter muscles in your jaw are muscles, and they can be grown just like any other muscle.

If you've ever tried building ANY muscle, you'll know that you should get enough protein and rest. To allow the muscle to grow.

All the normal muscle growth principles apply to your jaw muscles as well.

It has a woody, musky, vanilla-like taste. It's often described as a refreshing pine flavor.

Your order will arrive within 2-14 days depending on the country you are in.
