    Frequently Asked Questions

    Boric Acid is a white powder or colorless crystal that balances bacteria and yeast in the body. Boric acid has been used for over a hundred years for vaginal health support when it comes to keeping one’s vaginal flora balanced. A balanced vaginal flora = a healthy vagina!

    There are many different types of acids with ranging levels of pH (or potential of hydrogen, which is the measurement used to determine acidity). Many acids are “weak acids,” meaning they are safe to use. Common things in your house that contain weak acids are coffee, vinegar, and lemons.

    Similarly, boric acid is a very weak acid and has many health and wellness uses, so don’t be scared by its name! The Killer was formulated by a medical doctor and is manufactured with pharmaceutical-grade boric acid in our FDA registered facility according to CGMP standards – meaning, it’s safe to use as directed!

    A suppository is a specific supplement, medicine, drug, etc., that is typically inserted it into your body as opposed to swallowing it like a traditional pill. In the case of The Killer, this is a vaginal suppository, meaning it is inserted into the vagina. The Killer should not be swallowed or taken by mouth.

    The Killer is a vaginal suppository — not a pill you take by mouth. We know it looks similar, but this will be inserted vaginally. Boric acid, when inserted in the form of a suppository capsule, can help balance out bacteria to support a healthy vaginal environment.

    Wash your hands well to gently insert The Killer with your fingers into your vagina. It should be inserted a comfortable amount, which should be far enough that it won't have the chance to slip out. There is no need to alter the capsule in any way. Just pop it in — that's it! Within a few hours, the capsule will start to dissolve and getting to work. We recommend using it at bed time so it can be one less thing you have to worry about during the day as it can cause discharge.

    We recommend using only one suppository every 24-hour period.

    NO — The Killer is a vaginal suppository and is meant to only be inserted into the vagina. Do not insert The Killer into any other part of your body.

    The Killer capsule will dissolve over the course of a few hours. No need to take it out or touch it again after it's been inserted.

    The Killer helps to balance yeast and odor-causing bacteria. We recommend seeing your doctor first to determine the cause of any odor you may be experiencing that isn't normal to see if The Killer makes sense for you to use!

    We recommend waiting until the end of your period (or almost the end) before beginning to use The Killer.

    We recommend waiting 24-48 hours after using The Killer before having sex.

    How long you use The Killer depends on your body and your needs.

    You can use The Killer for as little as 1-3 days or for as long as 7-14 days (an entire box). As always, anytime you add anything new to your regimen, we recommend checking in with your doctor/healthcare provider to ensure it makes sense for you, and they can answer any more specific questions you might have!
