Deer Antler Fuzz?

I switched one of my gym memberships today to one that had childcare due to the fact that my two small grandchildren have moved in with me. I had been in about a month before to check it out. When I was there before the guy was asking me about where I work out and what I do. I do a lot of different things because I enjoy them. In addition to regular workouts, I cycle, ballroom dance, run and take aikido. Not on the same day, mind you.

So I go back in today to start my membership and I was all kinda...icky..because I had just come from crossfit. He looks at me and goes, "Oh I remember you. You're the one that works out too much. Have you cut back yet?" Uh..way to get on my good side. He insists that I have adrenal fatigue. From what i've read, It hasn't even been proven to be an actual thing. The jury is still out on that. He sits down to do my paper work and whips this little bottle out of his desk drawer and proceeds to tell me its a supplement. Something made from deer antler fuzz or fur, or fluff or something. He says it's great for adrenal fatigue and its just very beneficial and I should try it. I thought supplements were for things that are lacking in your diet. I'm probably pretty deficient in antler fuzz of any kind because I rarely eat it. I'm also deficient in tortoise toe nails. But I think I'm gonna pass. And I think I'll give this guy lots of space when I go to the gym.
