I'm a veteran lifter, so I don't get many DOMs in anything I do. Haven't noticed an increase in DOMs, maybe a hair. If I play an intense sport after lifting I'll notice tingly cramping in my legs a few hours later so it definitely does something. My personal experience with this stuff so far has been that it causes aches in injured/overworked areas but accelerates healing. Helped a minor LCL injury clear up completely! Used to tear my calves a lot, hasn't happened. Usually pull my neck every few months, hasn't happened. Have a torn bicep tendon that got set off lifting more lately but it healed in half the time. Suppose you could say my strength is up, but so is my weight recently so take that for what it is.
