I run very regularly, whether on flat terrain or trail, and at over 45, I’m still lucky to recover fairly quickly. For example, after a 25 km run with 500 meters of elevation gain, it usually takes me no more than three days to feel ready to go again.

What I can say is that after my first Synergy6 in November 2023, and now with the one I’m currently following, I’ve noticed a real improvement. I bought Synergy6 again because I genuinely feel like I’m recovering even faster than before.
I also believe it helps me better preserve my joint health, which is essential when you run on a regular basis.
