I can concur on the short-term benefits for longer sets as well as the shorter recovery. Creatine is just one of those no-brainer supplements.

It's safe, cheap, and long-term-study proven to be extremely effective.

You will want to increase your daily hydration (at least for otherwise healthy men, a good sign is that you're "peeing clear") as Creatine does increase water retention.

any recommendation for tendon/joint pain? I'm in my early 30s, and try to lift regularly, but my joints/tendons seem to be the limiting factor when lifting, and not really muscle tiredness/soreness
