Description
GDF-8 95% (1mg)Pharmacokinetics GDF 8s mechanism and role are well understood. Within the body, muscle is typically formed through the chemical signaling of cells called myocytes. These cells release endocrinological signals that prompt myogenesis, the formation of new muscle cells.[3] In the absence of GDF 8, this action could continue indefinitely. GDF 8s role is to bind to myocytes, and prevent the muscle forming signals from being sent.[1] Scientific Studies GDF

Dangerous.
Color: Purple
Died in about 2 days. Dogs chewed it to bits and then tried to swallow the pieces. Would not recommend for pet safety. I don't have big dogs, I have littler puppies (3 and 5 months) - would likely have died instantly with big chewers.

Disappointed they didn’t hold up long before pieces was being chewed off.
Color: Yellow and Purple
My minature poodle loved them till she started chewing pieces off of them so we had to dispose of them.

Good toy
Great toy for med dogs. A small one might have a bit of a hard time with the size but med and large dogs will love it. Thick plastic so they can’t pierce it quickly.
