Have received hydroxy colabamin from Amazon de German am I ok to use it Wasdelivered very quickly ,site all in English, and already had an account with them ,so was easy to get hold of . Just need to know from others that it ok before use. Know instructions on here how to inject. Have been months deciding whether to or not, but think time has come. Have tried sub lingual ,patches etc, but nothing comes close to the relief in neck and knees .
