I haven’t tried Klow- I mix my own Glow (50/10/10- 24 units daily) because I was already using the other 2 components when I fell and tore my meniscus -which really did speed up the healing; the first time I was on crutches a month and needed a cane for 2 more- this time, taking daily GLOW, I was using a cane for 3 weeks. Actually I take it back- I was doing 5 on/2 off then. I switched to daily after a conversation somewhere about whether you really need to take 2 off every week. I wish I’d thought to take pictures of my neck before I started using it, because it has really done a number on the crepey neck skin. I think it’s helping on the thighs- I had actually developed a sore on each side from the pinching, even trying multiple seat cushions and such. Those have healed and while it still pinches, it’s not near as bad. Yeah, I’m a skin bag. I’ve about decided I might need some skin removal if/when I get to goal and stop losing, but I’m a coward and don’t want to be in pain.
