Does this look like a fake? Bought off ebay. It came sealed. Nothing looked suspicious while unpackaging. There are some slight imperfections on the bottle. There are also only three ingredients listed on the box. On every box I have seen real and fake there is a huge list of ingredients. There is no serial number on the back. Is it real, is it fake, is it a tester? Please help a noob. Thanks in advance for any help.
