They're called Trim24 patches, I'll upload a pic with the info on the back. I've never tried them but the other day a girl come in asking for them saying she'd tried them a while back and they worked, so they must do something!
It lists the ingredients on the back:
Fucus vesiculosis - fancy name for kelp, which regulates your metabolism, gets rid of excess water and prevents cholesterol accumulating.
5HTP - appetite suppressant, is supposed to prevent carb cravings, but also increases serotonin which is your "feel good" hormone.
Guarana & Yerbamate - both stimulants to increase metabolism.
L-carnitine - burns fat to use as energy, breaks down carbs, can prevent lactic acid buildup
Flaxseed oil - rich in omega 3, which l-carnitine needs to be properly utilised.
Lecithin - binds to fat, breaks it up and passes through your water.
Zinc - I assume it's in there for the antioxidant purposes, helps with vitamin absorption.
Sorry for the dump of info
