Someone on Reddit asked if women over 40 are using something called "kisspeptin 10" to boost libido, and wanted to know dosage and how often to take it. That’s the whole story: it’s a question from an internet forum, not a scientific report or a clinical trial. There’s no study result attached to that post — just a person asking for others’ experience and dosing tips. Kisspeptin is a naturally occurring small protein in the body that helps control reproductive hormones. In plain terms, it acts like a messenger that tells a part of the brain to wake up the hormones that regulate fertility, menstrual cycles, and sexual function. "Kisspeptin 10" refers to a short fragment of that protein that researchers sometimes use in experiments because it can trigger the same hormone signals. It’s not a widely approved drug like Viagra or hormone replacement therapies. What research exists is mostly early-stage. Scientists have used kisspeptin in small clinical studies to study fertility and sexual arousal signals; some experiments showed brief hormonal changes or effects on brain activity related to sexual perception. But these studies are usually small — sometimes a few dozen people — and often done under controlled medical settings with careful monitoring. There isn’t robust evidence showing that taking kisspeptin boosts libido long-term, works reliably in women over 40, or is safe to use on your own at home. The Reddit question is asking for dosing information that such studies generally don’t provide for public self-use. Why it matters: libido and sexual function are common concerns as people age, and some look for alternatives to hormones or prescription drugs. If kisspeptin truly influenced sexual desire safely, it might offer a new approach for people whose libido has changed. Right now, because evidence is limited, the main relevant group is people interested in experimental treatments or researchers, rather than someone looking for an established, reliable therapy. Caveats and risks are important here. Kisspeptin compounds used in research are administered under medical supervision; their safety profile for long-term or unsupervised use isn’t established. Potential risks include unpredictable effects on reproductive hormones and menstrual cycles, interactions with existing hormone treatments, and unknown long-term consequences. It’s also not an approved medication for low libido, so dosing advice from internet threads is unreliable and potentially unsafe. Anyone curious should talk with a clinician — ideally one who knows reproductive endocrinology — before attempting anything, and be wary of products sold online that claim to be kisspeptin without regulatory oversight. Bottom line: Reddit is asking about kisspeptin 10 for libido, but the science is early and incomplete, and you should not self-dose based on forum posts.
