Interesting, as this seems to contradict previous studies that showed the opposite effect. Definitely worth keeping an eye on this and future studies. I've always known that AAS are known for building muscle faster than tendon, but even naturally, we tend to build muscle faster than tendon. I've seen several studies that do show adaptive response of tendons in many different AAS, so while I won't discount this research you presented, it doesn't seem to "fit". I'd llike to see the full study to understand their research better.

Nope, doesn't happen. And you can take that to the bank. I've done bloodwork with tren at 100/wk and at 200/wk. Bloods look great.
