Natural hormone production drops
The pill suppresses your normal ovarian cycle to prevent ovulation. As a result, your ovaries produce less estrogen, progesterone, and testosterone.
BIRTH CONTROL + DESIRE
Birth control shifts multiple pathways that can result in a lower sex drive for women. Keep reading to understand the connection — and what may get yours back.

ITS NOT YOUR FAULT
The pill suppresses your normal ovarian cycle to prevent ovulation. As a result, your ovaries produce less estrogen, progesterone, and testosterone.
Estrogen in your birth control increases SHBG—a protein that binds testosterone. As more gets bound up, less is available for your body to use.
Hormone evidence: Zimmerman et al., 2014
WHAT THIS CHANGES
Sex hormones act in the brain as well as the body. Changes in their signaling may affect sexual interest and response.
Estrogen and testosterone are two main drivers of sexual interest. Shifted balance and reduced availability commonly result in a lack of sex drive.
Estrogen and progesterone interact with serotonin signaling and stress-response systems. Hormonal shifts can have an intense effect on mood. A shifted mood, anxiety, and stress can all make it harder to get in the mood for sex.
Genital tissues respond to estrogen and androgens. Changes in that signaling may affect lubrication and blood-flow responses, contributing to dryness or less physical responsiveness in some women.
Serotonin: Larsen, 2020 · Stress: Hamilton & Meston, 2013 · Physical arousal: Handy et al., 2023
In the 2016 trial, the combined-pill group had lower average desire, arousal, and pleasure scores than placebo. Overall sexual-function scores were similar between groups.
A review of 42 studies found an average 61% reduction in free testosterone with combined-pill use.
You used to never be able to get enough. But now that “I need you” feeling is gone.
A lingering kiss. A flirty text. You'd think all day about what will happen when you get home.
They're hot. You love them. But getting in the mood takes effort.
“This shouldn't be happening to me”
AND THE ADVICE YOU KEEP HEARING?
But it may not be that simple.
You’re taking it for a reason. Giving up a method you trust can feel like trading one problem for another.
Pregnancy prevention matters. Giving up a method you trust is a big decision.
Maybe your pill helps with painful periods or acne. You don’t want those problems back.
You may have already switched methods and worked through side effects. Another round of trial and error can feel exhausting.
WHAT WE BELIEVE
Your reasons for staying on birth control are real. So is wanting to feel like yourself again.
We believe you should be able to have both
So we created Pulse.

Your sex drive is influenced by several pathways. Pulse brings them all together with one targeted formula.
Libifem® is included for sexual desire and arousal, with human research at the 600 mg daily dose used in Pulse.
Saffron + KSM-66® are included for sexual response, mood, and a healthy response to everyday stress.
DHEA + pregnenolone are precursors the body uses to make steroid hormones.

Explore the role, research, and exact daily dose of every active ingredient.
Libifem® Fenugreek Seed Extract600 mg
PRIMARY DESIRE + AROUSAL SUPPORT
The formula’s lead ingredient for desire and arousal.
Libifem® is the anchor of Pulse because the biggest thing we’re targeting is the loss of wanting. It’s here to support sexual interest, desire, and arousal — not just the physical side of sex.
Libifem® has been studied in women with low sexual desire, where it was associated with improvements in both desire and arousal. It also produced changes in sex-hormone availability, giving it a strong fit for the desire-first approach behind Pulse.
600 mg per two-capsule daily serving.
KSM-66® Ashwagandha Extract300 mg
STRESS SUPPORT
Helps create the lower-stress state where desire can come more naturally.
Desire is harder to access when your mind and body are stuck in stress mode. KSM-66® is included to help lower that background stress load and make more room for interest, spontaneity, and sexual engagement.
Standardized ashwagandha has been studied in women for sexual function, with improvements reported across arousal, lubrication, orgasm, satisfaction, and overall sexual-function scores. It also has human data supporting reductions in perceived stress and cortisol.
300 mg per two-capsule daily serving.
Saffron Extract30 mg
CENTRAL AROUSAL + MOOD SUPPORT
Supports the brain-based side of feeling turned on.
Wanting sex isn’t only about hormones. Your brain also has to feel engaged, receptive, and interested. Saffron is included to support that central side of arousal and sexual response.
Saffron has been studied in women at the same 30 mg daily amount used in Pulse, with improvements in overall sexual function and significant improvements in arousal and lubrication.
30 mg per two-capsule daily serving.
DHEA25 mg
HORMONAL PRECURSOR SUPPORT
Provides precursor support for hormone pathways involved in desire and sexual response.
Hormonal birth control can meaningfully change sex-hormone availability. DHEA is included to support the precursor side of that equation and give the body additional substrate for downstream androgen and estrogen pathways.
DHEA is a naturally occurring steroid precursor that can be converted into downstream androgens and estrogens. In oral-contraceptive research, DHEA supplementation has been shown to increase or preserve free-testosterone availability during contraceptive use.
25 mg per two-capsule daily serving.
Pregnenolone10 mg
UPSTREAM HORMONE + NEUROSTEROID SUPPORT
Broadens the formula’s support upstream of both steroid-hormone and neurosteroid pathways.
Pregnenolone sits near the top of the body’s steroid-production pathway, making it a natural complement to DHEA. It’s included to broaden Pulse’s precursor support rather than relying on a single downstream pathway.
Pregnenolone is an upstream precursor involved in the production of multiple steroid hormones, including DHEA, while also participating in neurosteroid pathways involved in brain signaling and nervous-system function.
10 mg per two-capsule daily serving.
YOUR DAILY ROUTINE
A small daily habit, with room for the rest of your life.
WHAT TO EXPECT
Pulse works through consistent daily use. Its support builds over time, and you notice the change where it matters: in your sex life.
Not because you’re trying to. Because it’s crossing your mind on its own more often.
You’re initiating more, leaning in faster, or feeling that “I want you” energy showing up again.
A look, a touch, or a moment can turn into something more — without everything having to be planned.
When intimacy starts, you feel more mentally engaged — like desire is meeting the moment instead of lagging behind it.
Take Pulse every day and give the change room to build. Look for more sexual thoughts, more interest in initiating, and an easier time getting into the moment.
You’re not chasing the moment.
The moment starts finding you again.
KEEP WHAT WORKS
Compatibility shouldn’t be a footnote. Here are the questions we’d want answered too.
No. Pulse does not make your birth control less effective.
It supports desire and arousal alongside your contraception; it does not replace or change your method. If you use prescription medication or manage a health condition, you can review the ingredient list with your doctor.
Pulse does not contain added estrogen, progesterone, testosterone, or a contraceptive hormone.
It does contain DHEA and pregnenolone, which are upstream steroid precursors. Think of them as building blocks your body can use in downstream hormone pathways, rather than active sex hormones added to the formula. Their role is precursor support, not contraception or hormone replacement.
That depends on the medication.
If you take prescription medication, have your doctor or pharmacist review the fully disclosed ingredient list before use.
No. Pulse is designed to work alongside the birth control you value while supporting desire and arousal.
It is not a recommendation to stop, switch, or alter your contraception, and it does not replace your contraceptive method.
Know what you’re taking.

BEFORE YOU TRY PULSE
YOUR SEX LIFE
Pulse is designed to support sexual desire, arousal, spontaneity, and feeling more mentally engaged in sex again.
The formula is desire-first: Libifem® supports desire and arousal, saffron supports central sexual response, KSM-66® supports a lower-stress state, and DHEA + pregnenolone provide hormonal precursor support.
With consistent daily use, support builds over time. You begin to notice it in your sex life: sex crosses your mind more often, you feel more interested when intimacy starts, and initiating or getting into the moment feels easier.
It is a gradual shift toward desire and arousal feeling more natural and easier to access.
That is exactly where Pulse is most intentionally focused.
Pulse was built around the experience of not wanting sex the way you used to. Libifem® is the primary desire-focused ingredient in the formula, with saffron, KSM-66®, DHEA, and pregnenolone supporting complementary parts of sexual response.
Yes. Pulse is designed to support both desire and arousal.
Desire and arousal are connected, but they are not identical. Libifem® and saffron are both included because Pulse is designed to support not only sexual interest, but also the process of becoming more mentally and physically engaged once intimacy starts.
Lubrication is one part of sexual arousal, which Pulse is designed to support.
Saffron has been studied in women experiencing fluoxetine-associated sexual dysfunction at 30 mg daily, the same daily amount used in Pulse, with significant improvements reported in arousal and lubrication.
Pulse is primarily focused on desire, arousal, and sexual engagement.
Standardized ashwagandha has also been studied in women with improvements reported across several sexual-function domains, including orgasm and satisfaction.
No. Pulse supports healthy desire and arousal so that wanting sex may feel more available and natural—not overwhelming or artificial.
No.
Pulse is designed for consistent daily use, not as an on-demand supplement you take right before sex.
Take two capsules once daily, preferably with food.
Pulse is a daily supplement, not something you take right before sex. Take it consistently and let the support build over time.
The change shows up in your sex life: more sexual thoughts, more interest in initiating, and arousal and engagement that feel easier to access. Notice how those moments develop as daily use becomes part of your routine.
Your 30-day money-back guarantee begins when your order is delivered, giving you time to try Pulse consistently and check in with your experience.
Yes.
We recommend taking two capsules with food once daily. Taking supplements with a meal may also help reduce the chance of stomach or GI discomfort.
No.
Take Pulse every day whether or not you plan to have sex. It is designed to support desire and arousal over time rather than only on days you are sexually active.
That is normal.
Sexual desire can shift with stress, sleep, mood, your relationship, health, your cycle, and other factors. That is why we recommend looking at your overall experience after consistent daily use instead of judging Pulse based on one day or one sexual encounter.
THE FORMULA
Each two-capsule daily serving contains:
Every active ingredient and every amount is disclosed on the label.
Because we wanted the formula to address more than one part of desire.
Together, they give Pulse a wider desire-first architecture instead of relying on one single mechanism.
No.
There is no hidden blend, no mystery “complex,” and no undisclosed amount.
You can see exactly what every active ingredient is and exactly how much you are getting.
Libifem® is the anchor of Pulse because the formula is built around wanting sex again.
It is a standardized fenugreek extract studied in women reporting low sexual drive at the same 600 mg daily amount used in Pulse, with improvements reported in sexual desire and arousal.
Because sexual response is not only hormonal.
Saffron is included to support the brain-based side of sexual response and arousal. It has been studied in women experiencing fluoxetine-associated sexual dysfunction at the same 30 mg daily amount used in Pulse, with improvements reported in overall sexual-function measures, including significant improvements in arousal and lubrication.
Because stress can make desire harder to access.
KSM-66® ashwagandha is included to support a lower-stress mental and physical state, helping create more room for sexual interest, spontaneity, and engagement.
Standardized ashwagandha has also been studied in women for sexual function, with improvements reported across several sexual-function domains. Its role in Pulse is stress support.
DHEA is a naturally occurring steroid precursor that the body can use in downstream androgen and estrogen pathways.
Hormonal contraceptives can change androgen availability, including increasing SHBG and reducing circulating free testosterone. DHEA has been studied alongside combined oral contraceptives for its effects on androgen availability during contraceptive use.
DHEA in Pulse does not reduce the effectiveness of your birth control. Its role is precursor support for downstream hormone pathways, not to block or replace contraceptive hormones.
As with any supplement used alongside prescription medication, it is a good idea to review the fully disclosed ingredient list with your doctor.
Pregnenolone is an upstream steroid precursor and also participates in neurosteroid biology.
It is included to broaden the precursor-support side of Pulse, supporting upstream hormone-related and neurosteroid pathways rather than relying on DHEA alone.
Pulse does not contain added estrogen, progesterone, testosterone, or a contraceptive hormone.
It contains DHEA and pregnenolone, which are naturally occurring steroid precursors. Think of them as building blocks the body can use in downstream hormone pathways, rather than active sex hormones added to the formula.
Their role in Pulse is precursor support, not contraception or hormone replacement.
That is not how we describe it.
Pulse is not based on a vague “hormone balancing” promise.
DHEA and pregnenolone provide precursor support, while Libifem®, saffron, and KSM-66® address desire, arousal, central sexual response, and stress-related sexual wellness.
Because Pulse was built around desire first, not blood flow first.
The primary problem we are trying to address is the loss of wanting, sexual interest, spontaneity, and engagement. That is why the formula prioritizes desire, central sexual response, stress support, and hormonal precursor support instead of making a vascular ingredient the centerpiece.
Take two capsules once daily, preferably with food.
Each bottle contains 60 capsules, which equals a 30-day supply.
BIRTH CONTROL + SAFETY
No. Pulse is designed to work alongside the birth control you value while providing separate daily support for desire and arousal.
It is not a recommendation to stop, switch, or change your contraception, and it does not replace your contraceptive method.
No. Pulse does not make your birth control less effective.
It supports desire and arousal alongside your contraception; it does not replace or change your method. If you use prescription medication or manage a health condition, you can review the ingredient list with your doctor.
No. DHEA in Pulse does not reduce the effectiveness of your birth control.
DHEA has been studied alongside combined oral contraceptives. Its role is to provide precursor support for downstream hormone pathways, not to block or replace contraceptive hormones.
As with any supplement used alongside prescription medication, it is a good idea to review the fully disclosed ingredient list with your doctor.
Pulse is designed as separate daily support alongside your contraception, whether you use the pill, an IUD, an implant, a ring, a patch, or an injection.
Pulse does not reduce the effectiveness of these birth-control methods. It does not replace or change your method, and you can review the ingredient list with your doctor.
Pulse can still be relevant.
Sexual desire can be influenced by stress, mood, sleep, medications, health, pain, relationship context, hormonal changes, and many other factors.
Hormonal birth control is one possible contributor, not the only explanation. Some women report worse sexual function on contraception, while others experience no change or even improvement.
Pulse is built around systems involved in healthy desire and arousal, so birth control does not have to be the only reason you are experiencing changes for the formula’s overall approach to be relevant.
That depends on the medication.
If you take prescription medication, show your doctor or pharmacist Pulse’s fully disclosed ingredient list before use.
