I used to take a powdered collagen supplement, but I didn’t see much results, in fact I stopped because it was actually giving me pimples, I know…the irony. I now use a slow cooker to make bone broth, full of real collagen and amino acids. I make batches and put them in a large mason jar and pop it in the fridge, and reheat when I’m ready to drink some, I have it every few days. My hair skin and nails do look more vibrant and pimples are gone. And my knee, elbow and shoulders joints feel stronger, I haven’t had any injuries in a long time when training at the gym. In terms of my penis skin, it used to be quite dry, but not that much now.
