What are these ? how or do they work

By the way ,I can FIT into my favorite pair of Calvin Klein Shorts that I have had hanging on the wall for my inspiration There was no chance that they would even go on just 2 months ago so I'm very HAPPY
I havent fit in them for 7 years!!

I've no clue what they are. They're probably too good to be true!

They don't work. If they worked, doctors would be prescribing them and they would not have to advertise.
