 ✅ 3 Project Jawline Alternatives
 🏁 Summary



The jawline formula: mewing, chewing and slimming. Step 2 is all about using jawline exercise equipment to build your masseter muscles in your jaw.

   If you're been trying to improve your jawline with mastic gum, you may have heard about Project Jawline Gum. It's been around for a while now and somehow they're still in business.

   They don't have any real reviews or decent transformation pictures, but it's mastic gum. It's known to work.

Does Project Jawline Work? Will it Build Your Jaw Muscles?

There's no doubt that chewing Mastic Gum will add mass to your jaw. Think about it: our ancestors chewed bark, roots, leaves and nuts for 6000 years.

   They never did facial exercises. They ate tough meat and hard foods that weren't boiled floppy and filled with preservatives. They trained jaw heavy everyday. 

   In recent years we've proven that chewing tough foods will hypertrophy your masticatory muscles – mainly your masseter. This 2011 study for example.

   I've seen dozens of impressive transformation photos on reddit and other "looksmaxxing" forums. In general, you should be skeptical with these results photos. Changes can be a result of multiple factors.

That said, I'm 100% certain that Mastic Gum is one of those contributing factors.

3 Better Alternatives to Project Jawline

(Use These Instead!)



  • 🥇 The JAWLINERS: these are the best molar-based jawline exercisers available today. They are both safe and effective. Start with the Beginner and move up to higher resistances as your jaw and face gets stronger.
  • 🥈 Jawliner Gum: a mint flavored gum that has been created to be 15x harder than regular chewing gum. It's cheaper than mastic gum but loses its taste faster and doesn't come with the same health benefits.
  • 🥉 Mastic Gum: this is 10x harder than regular chewing gum. It's a 100% natural tree sap harvested on the Greek island of Chios. It's a convenient way to train your masseter muscles while you are working, driving, studying or doing anything for that matter.
