Ive noticed a couple more threads talking about Tylan lately and I wanted to give this one last update. The snake in question is still doing amazing and is my best eater. She is over 1,000 grams now and since the Tylan injections has never shown a sign of RI again. If something changes with her health or the RI comes back I will update this thread, but it has been almost a year so I can conclude that she suffered no visible side affects and was healed fully.
