Tip of my tongue, but about 5-6 years ago, I read a series of books following women (I think at least three) who'd gained superpowers based on menopause symptoms after their "Alternative Medicine" doctor, an older Chinese woman, gave them herbal medicine to try. One woman was Hispanic, and woke up a man, with super-strength and maybe enhanced toughness. I remember her husband, also Hispanic, had a lot of trouble with the change, although he eventually warmed to the idea of continuing to be sexually active with her. One woman gained fire powers. I forget what the third one gained. I want to say it had something to do with manipulating her weight, with some early scenes having her wearing diving weights around her waist to avoid floating.
Eventually, they meet each other and team up, especially when they realize they all have the same doctor, who it turns out was using them as guinea pigs for experimental treatments outside of scientific understanding, but which she was trying to study scientifically. I remember it involved foreign herbs, and I think some sort of jade device that the protagonist women steal at some point for leverage.
The scientist who transformed them (maybe named Jasmine?) is presented as somewhat sympathetic with her apparently having been a chemical genius, but held down in her career due to her sex. Now, older, she's more established, but feels like she's running out of time to make her big break. Ironically, I think a lab accident causes her to deage to a teenager, which means people find her even less credible. I believe the search for her covers the first book. At the end, due to the deaging, she slipped by the police.
I think later books have the scientist kidnapped by organized crime, and the heroes trying to retrieve her both so that they can be cured (if they still want to, as some of them are getting used to having unaccustomed power) and also to keep powers out of the hands of criminals. I also think that the Hispanic woman's husband gets shot at some point when he tries to get involved in a fight to assuage his feelings of masculine inferiority to his wife.
The books were electronic, in English, and seemed well-written despite a somewhat silly premise. They seemed novel length, about 200 pages each, at least a trilogy of books. I have too many books in my Kindle history to really browse, so that hasn't helped.
