Most cdc will take spare stock back ,this is in the hope of cutting down on them been sold privatly .there are some medical conditions which are not compatiable with cd or peeps who are bellow bmi25 should not ss as your body has to have more protien (i think ) so it doesnt start to loss muscle .This is why private sales are not a good idea .
Good luck with your second part of your journey hun hope your cdc will buy them back as ebay has stopped the sale of vlcd i think xxx
