The first time I brought home a jar of Penetrex and set it on my nightstand, my husband laughed. Yes, I know — the name, not to mention my preference of keeping it bedside, makes it seem like it'd be for something more thrilling than muscle and joint aches. Over the years, I’ve tried many other muscle relief topicals with varying actives and much more demure names — but Penetrex is one that I always seem to return to for my run-of-the-mill back and neck aches. I started to think of it as my (saucy sounding) secret weapon. That's why I was both surprised and validated when I realized it had more than 70,000 positive ratings on Amazon. Not only that, but right now it’s up to 20% off for Amazon Big Deal Days.
Here’s what to know about how Penetrex works and what other reviewers are saying about it.
