Paws the vote is in and it got three out of three
Three puppies voted paws up for taste and a little bit of longevity. Now as for value for money. I know how much better than rawhide treats. But I’d like to see the price come down and more chewy’s inside the bag

So so small! Not worth $
The images in Amazon are nothing like what the product is. The pretzels and rings are minuscule. My two pit/lab mixes will eat one in about 30 seconds. So disappointment. Not worth the $ for what you’re getting. I tried to return items which are individually wrapped but they do not allow returns on these products. I have not opened any of them and still not able to return. If you have a dog under 15lbs these may work! If you have a large breed don’t bother. I’m so disappointed. Pictures above is the product next to a small milk bone biscuit (for reference).

Clean & quality but taste, meh
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
I’ve ordered this product twice now. I do a wide array of workouts from weights to running to multi-functional. I’ve taken aminos from different companies for a long time but started to finally really research & felt much safer taking Thorne. The flavor isn’t the best if you add too much water. I’ve always added around 20oz to my intra-workout aminos with no problem but this one will get watered down. I adjusted and it’s been good. I’m also used to awful tasting soups and just powering through worse and this flavor is better than stuff I took up till the last few years. Newer people to using supplements might not like the flavor at all but trust me all workout supplements used to be awful. My recovery & muscle growth/lift gains have remained the same to the other products I’ve used with more mystery ingredients so there was no drop off there. I’m okay with taking a step back on taste and variety rather than putting mystery crap in my body from lesser regulated big companies. Product quality wins this for me & I’ve heard from multiple non-Thorne associated experts that vouched for Thrones testing.
