Could you tell us more? Where did you buy it? How much did you give him? How did you give it to him? How long did it take before you noticed an improvement? We are trying coconut oil, but would like to add anything that would help. Thanks!!
I’m not really sure what XPS is, I know there’s an XP, XPC and YP...
I got mine from ebay, but my dad lives in India, so he got his stuff direct from the distributor. He would put it into his morning cereal or coffee. I can swallow stuff, so I just put it in my mouth and wash it down with water.
I think it took him a couple months to notice an improvement. YMMV of course, but it’s worth a shot.
