Background

Encoded by the ob (obese) gene, Leptin is an adipose-derived cytokine that suppresses appetite and increases thermogenesis. The absence of leptin (or its receptor) leads to uncontrolled food intake and resulting obesity. Leptin exerts its anorectic effect via signaling through a hypothalamic receptor termed OB-R. Leptin has been shown to reduce body weight, food consumption, and plasma glucose levels in various in vivo models. Recombinant Human Leptin is a 16.0kDa protein containing 146 amino acid residues.

Finally, an Indestructible Toy My Dog Loves!
Color: Red
I have a dog who usually destroys all toys, even the hardest toys I have ever bought. However, this bone toy has proven to be indestructible! Not only does my dog ​​love it, but he keeps it playing for an hour and a half at a time. I highly recommend this toy and plan on purchasing a second or third.

Wonderful!
Color: Red, Color: Red
My dog loves this toy! It keeps her engaged for long periods of time. She’s an aggressive chewer and hasn’t been able to break it or shred it at all. The material is very hard and I feel safe when she is chewing it unattended. Worth every penny to have peace of mind!

Might be OK for others but my dog wants nothing to do with it
Color: Red
Might be OK for others but my dog want's nothing to do with it. I tried multiple things, treat, fetch, nothing. She doesn't even want to smell it. It appears to be heavy plastic with rubber wrapped around the middle. Nothing about it that attracts a dog.
