Greco Gum vs Titans Jaw: an honest comparison comes down to what you want from a tin. Both sell pure Chios mastic resin. Greco Gum is the larger, longer-reviewed brand, with soft nuggets, firm droplets and a gut-health line. Titans Jaw sells sorted tears built for jaw training at a lower price per tin, plus a 1 lb bulk bag.

What does each brand actually sell?
All brands sell raw Chios resin, but Greco Gum has a more varied portfolio of products including chewing gum, capsules and lifestyle. Titans Jaw only sells chewing resins in 3 forms.
Here’s the line-up, using each brand’s own listed prices as of November 2026:
| Brand | Product | Form | Size | List price |
| Greco Gum | Nuggets (Klassiko) | Larger pieces, marketed as soft | 45 g tin | $45.98 |
| Greco Gum | Droplets (Klassiko) | Small pieces, marketed as firm | 45 g tin | $41.98 |
| Greco Gum | Nuggets or Droplets (Mikro) | Same forms, trial size | 15 g tin | $28.98 / $24.98 |
| Greco Gum | Mastic gum powder | Capsules for swallowing | 60 capsules | $36.98 |
| Titans Jaw | Small Tears | Sorted small tears | 28.35 g tin | $19.99 |
| Titans Jaw | Medium Tears | Sorted medium tears | 28.35 g tin | $20.99 |
| Titans Jaw | Melted Mastic Gum | Melted resin pieces | 1 lb bag | $39.99 |
The naming differs, the resin doesn’t. Greco Gum calls its pieces nuggets and droplets. We call ours tears, which is the traditional Chios word for the drops of resin that harden on the tree. Either way, the product is resin from the mastic tree, sold by piece size.
Greco Gum adds a capsule line. Powder in capsules is a supplement you swallow. So it isn’t part of a chewing comparison, even though it shows up in the same search results.
Who is each brand built for?
Greco Gum is built around gut and oral health, and Titans Jaw is built around jaw training. That one difference explains most of what shows up on each site.
Greco Gum’s angle. Greco Gum describes its nuggets as “soft and easy to chew” and leads with oral health and digestion. It sells a starter pack, a “Gut Health Protocol” bundle and capsules, and it accepts HSA and FSA payments on eligible orders through a third-party service. In other words, it’s speaking to people who want mastic as a daily wellness habit.
Titans Jaw’s angle. We sort tears by size so the chew stays consistent from piece to piece, which matters when you’re training a muscle. Small Tears are the starting point. Medium Tears are the step up once small ones feel easy. Our guide to the difference between small and medium mastic tears explains why size is the variable that changes the chew.
What neither brand can promise. No published study shows mastic gum reshaping a jawline. Our own post on what the jaw training research says sets realistic expectations before you buy from anyone.
How do shipping, bundles and guarantees compare?
The purchase terms differ more than most buyers notice. Here’s how a straight brand comparison of the checkout looks:
- Free shipping. Titans Jaw ships free in the US on orders over $50. Greco Gum ships free on orders over $100.
- Multi-buy discounts. Greco Gum takes 10% off when you buy four tins and offers subscription pricing that lowers the per-tin cost. Titans Jaw’s bulk option is the 1 lb melted bag.
- Guarantees. Titans Jaw offers a 30-day money-back guarantee on all orders. Greco Gum offers a swap or full refund within 30 days of delivery on a first order.
- Payment options. Greco Gum accepts HSA and FSA payments on eligible orders. Titans Jaw doesn’t currently offer that.
What that means in practice. A first-time buyer trying one tin pays shipping at Greco Gum unless the order clears $100. On the other hand, a buyer with HSA funds set aside has a reason to lean toward Greco Gum. Meanwhile, a buyer who chews daily gets the most from a single bulk order that clears either free-shipping line.
Where do premium mastiha brands fit among the alternatives?
Greco Gum and Titans Jaw sit in the same group: premium mastiha brands selling pure Chios resin in tins, direct to US buyers. Anyone looking to compare Greco Gum alternatives has three other groups to consider.
Greek producer packs. These come straight from the Chios supply chain in small foil or paper packs. Origin is rarely in doubt, but tear sizes are mixed in the same pack, so the chew changes from piece to piece.
“Mastic flavor” gums. These are gum base with mastic flavoring, not resin. They chew like ordinary gum and cost less per piece, which is exactly why they’re a different product.
Capsule supplement brands. These are powder in a capsule. They’re useful for people who want mastic without chewing, but they do nothing for chewing muscles.
Why origin is the common thread. Real mastiha comes only from southern Chios, and UNESCO lists the know-how of cultivating mastic on Chios as intangible cultural heritage. Both brands here claim Chios origin. Our best mastic gum buyer’s guide covers how to check that claim on any label.
Which brand should you choose?
Choose by how you plan to use it. When people ask “greco gum vs titans jaw which is better,” the honest answer is that each one wins a different use.
Choose Greco Gum if you want a softer chew, a gut-health routine with capsules on the side, HSA or FSA payment, or a brand with a long review history.
Choose Titans Jaw if you’re chewing for jaw training, want sorted tear sizes you can step up through, want the lowest list price per tin, or chew daily and want a 1 lb bag.
If you can’t decide. Start with the smallest tin of each. Greco Gum’s 15 g Mikro tin and our 28.35 g Small Tears tin together cost less than $50, and two weeks of chewing tells you more than any review. Then notice which one you reach for on day ten, not day one.
On the “best” question. Searches ask “is greco gum the best mastic gum,” and no single brand is best for every buyer. The best tin is pure Chios resin, with one ingredient and a clear net weight, in the piece size that matches how you chew.
Where is the cheaper mastic tin the worse buy?
A low price only helps when the resin is real and the tin matches your use. These are the trades to watch with any brand:
- A small tin with a low sticker price. It looks cheap until you divide by the grams.
- Mixed piece sizes for jaw training. The pack costs less. Then the resistance changes with every piece.
- Bulk resin you won’t finish. A large bag is cheap per gram. However, it only pays off if you chew daily.
- A marketplace reseller. The listing looks the same. Meanwhile, the price can be marked up well above the brand’s own site, with no clear return route.
Where cheaper wins. If you chew every day, bulk melted resin is the lowest cost per gram of real mastiha either brand sells.
Which red flags apply to any mastic brand?
Watch for these before you order from anyone, including us:
- No Chios origin stated on the label or product page.
- More than one ingredient on a product sold as pure resin.
- No net weight in grams or ounces.
- Jawline promises with before-and-after photos.
- Resin sold only through third-party marketplaces at inflated prices.
- No refund policy you can read before checkout.

Frequently asked questions
1. How do the brands differ?
The brands differ in focus: Greco Gum leads with gut and oral health, and Titans Jaw leads with jaw training. Anyone asking how does greco gum compare will find softer nuggets, firm droplets and a capsule line, while Titans Jaw sells sorted small and medium tears and a 1 lb melted bag. What makes greco gum different is its wellness positioning and wider product range, not a different resin.
2. Which is better value per gram?
Titans Jaw is better value per gram at list price. Our 28.35 g tins work out to about $0.71 to $0.74 per gram, while Greco Gum’s 45 g tins run about $0.93 to $1.02 per gram before subscription discounts. For anyone asking is greco gum worth it, the answer is yes if you value its softer chew and wellness range, while the 1 lb melted bag at about $0.09 per gram is the lowest price per gram of either brand.
3. Is the resin sourced differently?
No, both brands sell pure resin from mastic trees on Chios, Greece. Greco Gum describes itself as based on the island with warehouses in the US. Titans Jaw’s resin is hand-harvested by Chios growers and independently lab tested for purity and contaminants.
4. Which chews harder?
Titans Jaw Medium Tears and Greco Gum Droplets are the firmer chews, while Greco Gum Nuggets are marketed as soft and easy to chew. Hardness comes from piece size and grade, not from a different resin. Temperature matters too, since resin softens in heat and stays firmer when cool.
5. Which has better reviews?
Greco Gum has the larger review base, showing 4.79 stars across more than 1,200 reviews on its own site. Titans Jaw is a newer store and doesn’t yet have product reviews on its site. Treat any greco gum review on a reseller site with caution, since some marketplace listings carry lower ratings and higher prices than the brand’s own store.
