I realize research on Tren's effect in humans is likely very limited or non-existant, but I'm wondering if there is any data regarding whether tren has a negative or positive impact on collagen synthesis. If there isn't any hard data, what are you thoughts in regard to it's effects on joint and tendon health? I realize it is a nandrolone derivative, but the two already have so little in common I wouldn't be comfortable assuming it shares nandrolone's positive effects on joint and tendon health.

Any input welcome, although be sure to label speculation accordingly. Thanks guys.
