Yes, it is for females as well or any one interested in improving overall health markers whether on anabolics or just for everyday health. By that I'm referring to Kingsguard mainly. TUDCA is not needed when not cycling liver toxic compounds and Arimacare has Arimastane included which may modulate estrogen levels some. KG has some estro control as well. VO2Maxima could offer a female's perspective on the use of these for females.
Kingsguard would absolutely be good to use on cycle as cycle support (or even as just a general health supplement).
As far as PCT goes (which is after, not during), you aren't trying to restart HPTA the way a guy is. Women do have natural test, but it's a very different process. There's varying opinions on females and PCT, but in general, it's not the same as a PCT for guys. Not everyone utilizes a PCT, though there is the possibility of depression and estrogen rebound, so if you do choose to run a PCT, you'd probably be fine with something OTC (e.g. K1ngs Blood). If she does choose to run a SERM too, go super low dose because a higher dose could potentially have a greater impact on her hormones than the cycle itself. Please continue to research this more on your own and collect more information before making any decisions there. I don't have a ton of knowledge regarding Winstrol, so you may want to get advice from someone who does. But based on these questions, I feel like this is her first cycle...why Winstrol? It's not the worst choice for women, but it also does tend to have a higher risk of virilization sides than some others.
