The packaging the parcel was mailed in did not provide any protection for the supplements. Upon opening the package there were a couple capsules that had burst open leaving everything dusted in powder. I haven't started taking them yet so I don't know if I can tell a difference from Primal Queen. I do like that Primal Queen includes little peppermint scented inserts to help make the capsules more palatable...providing something like that would definitely help.
