I have some stuff that seems to have worked for friends of mine it says ooops "winny-v" on the label. Seems to be sealed well and looks real, but is it? Has a red flip off tab before you break the seal. This is my first time using it, trying to cut up and lose some weight. Coming off an injury and looking to lose before building for gain. Any suggestions of a way to stack this? I assume it's good only by the results my friends have gotten.
