Tender ones, containing more blood and less ossified, are antler; old ones, containing less blood and severely ossified, are antlers. When distinguishing between sawing and chopping antler, we do not talk about the harvesting method, but the name. Saw antler is deer antler, just pure velvet antler, while chopped antler is also called beheaded antler. Cutting off the deer head and antler together is called beheaded antler. In other words, the antler with a deer head is called chopped antler, and the antler without deer head is called saw antler.
For a thin body, there are many ways to eat, but it needs to be done step by step, not too hastily, and needs to be supplemented slowly. For specific consumption methods, I suggest you just read my previous answers in this regard. Most of my answers are about velvet antler. Some of them are about issues you didn’t mention. It may also be useful to you if you take a look. Helpful and guiding. If there's anything you still don't understand, ask again and we'll discuss it further. But you must pay attention to the amount. From small to large, your consumption needs to be half less than the amount I gave to ordinary questioners. I am a deer farmer and hope this helps.
