I don't mean to burst your guys' bubble, but seeing as this is not a pharmacuetically created/tested steroid, the feedback you are going to get here, or on any board is conjecture. Somebody may say it damaged there tendons, others no. It's effects are supposed to mimick Tren, keyword effects. As you can see nobody really knows what it's chemical make-up is exactly, and therefore can't exactly tell you what it will do to your body.
