Mountain Eagle, of course, had never seen a 'mutated' brown bear, but he had seen 'monsters' concocted by humans.
Lean meat powder, steroids, and the animal medicine Group Dragon, commonly used by almost everyone in the bodybuilding community, had created a bunch of muscular monsters...
Because the use of Group Dragon requires it to be paired with estrogen, those seemingly huge muscle monsters would eventually suffer from cardiovascular diseases, erectile dysfunction, and widespread acne as side effects over time.
Most importantly, when steroids are used excessively, people become aggressive and irritable; they can easily burst a muscle without needing Viagra. Aside from their manhood not functioning well, every other part of them is absolutely the epitome of masculinity!
There is even more outrageous stuff, such as the Devil Meat Cattle, the Belgian Blue Cattle bred through selective artificial crossbreeding, and the Whippet dogs in dog racing competitions...
