And now for a different kind of progress pic: THM can strengthen your nails (and hair...and skin!)
The effects of collagen on nails. I have always had strong nails but with hard nails they snap and crack when I hit them on things. Now they are very strong and can take a hit or 2. My longest nails are easily 1/2 inch off my finger tip.
My middle finger on my right hand started to crack (top pic) so now they all get chopped back down.
