When stress gets in the way of your sex drive, start there.

The Stress-to-Strength Stack is a three-formula day-and-night protocol designed to support daytime stress management, overnight recovery, and male sexual performance.

Stress-to-Strength Stack

StoneBoneβ„’ + BlackAshwagandhaβ„’ + NightEdgeβ„’

Three-Formula System Β· Performance Β· Cortisol Control Β· Sleep & Recovery Β· 30-Day Supply per Formula

Ryan D., 41

β€œI knew stress was the problem. I just didn’t have a system for it. BlackAshwagandha brought my cortisol under control. NightEdge gave me back the sleep I’d been missing for two years. And with both of those working, StoneBone could actually do its job. It took addressing the cause before the symptoms started clearing.”

Built for the same man.

TBΓ΄ makes underwear for men who care about comfort, confidence, and how they show up. Marco’s Grounds brings that same intention to sexual health and everyday performance.

This collaboration pairs TBô’s comfort with a three-formula day-and-night protocol: StoneBoneβ„’ for the performance foundation, BlackAshwagandhaβ„’ for daytime stress support, and NightEdgeβ„’ for sleep and recovery.

The Stress-to-Strength Stack is built for you if:

  • You notice your drive slipping during demanding, stressful periods.
  • You’re sleeping poorly and feeling depleted the next day.
  • You want one morning-and-night routine supporting stress management, sleep, and sexual performance.
TBΓ΄ and Marco’s Grounds: Stress-to-Strength Stack with 30% off

Your morning-and-night routine.

Stress builds through the day. Recovery happens at night. The Stress-to-Strength Stack supports bothβ€”and protects the performance foundation underneath them.

MORNING

StoneBoneβ„’

Support the performance baseline

The daily performance layer of the stack, supporting drive, blood flow, and physical readiness.

Take 2 tablets in the morning with a full glass of water.

MORNING

BlackAshwagandhaβ„’

Support the daytime stress response

650 mg certified organic Ashwagandha root with 5 mg organic Black Pepper, built to support cortisol regulation and the body’s response to sustained stress.

Take 1 capsule in the morning with StoneBoneβ„’.

BEFORE BED

NightEdgeβ„’

Make the night count

A nighttime formula designed to support sleep quality, nervous-system calm, and the recovery your body needs before the next day begins.

Take 2 capsules 30–60 minutes before bed.

Why the three work together.

StoneBoneβ„’ supports the performance foundation. BlackAshwagandhaβ„’ supports daytime stress management. NightEdgeβ„’ supports sleep and overnight recovery. Together, they form one morning-and-night routine.

Morning: StoneBone and BlackAshwagandha. Night: NightEdge.

The part of performance you can’t wear.

TBΓ΄ can handle the comfort and support you wear.

But stress doesn’t clock out when you do.

You can finish work and still feel switched on. Your body is home, but your head is still running through deadlines, problems, and tomorrow’s list.

Then the night takes the hit.

You sleep, but don’t feel fully restored. You start the next day with less in the tank. By evening, there is less energy left for yourself and the parts of life where you actually want to feel switched on.

One rough day is normal. The problem is when it becomes the baseline.

If stress and poor recovery are part of what changed your drive, supporting performance alone leaves part of the pattern untouched.

The stress loop: long loaded days, hard to switch off, recovery falls short, less left in the tank

Give your body time to catch up.

The Stress-to-Strength Stack is designed for consistent daily use. Think less instant boost. More building a better baseline.

The four stages: Settle In (days 0–14), Stabilize (days 14–30), Rebuild (days 30–60), and Strengthen (days 60–90+). This is a guideline, not a guaranteed schedule. Individual results vary.

The stress-testosterone cycle. And how to break it.

Cortisol and testosterone exist in a direct inverse relationship. When cortisol is chronically elevated β€” the predictable result of sustained overload β€” the body redirects the hormonal resources that would normally go to testosterone production toward the stress response. Over weeks and months, this creates a compounding deficit: lower testosterone, less drive, less energy, and a sleep disruption that prevents the overnight recovery that could reverse it.

The Stress-to-Strength Stack addresses both sides of the cortisol cycle. BlackAshwagandhaβ„’ manages daytime cortisol through the HPA axis before it can accumulate to suppressive levels. NightEdgeβ„’ supports the deep sleep that allows cortisol to clear overnight and testosterone production to proceed. StoneBoneβ„’ restores the performance and drive baseline that the cortisol suppression has been eroding.

The three formulas.

StoneBoneβ„’

Sexual Performance & Blood-Flow Complex

The performance layer Β· Take morning, every day

The performance foundation that the other two formulas make more effective. Drive, blood flow, and physical readiness β€” the daily formula that restores the performance baseline that stress and cortisol have been suppressing. 12 active ingredients including Longjack (400mg), L-Arginine (250mg), and the Ginseng-Eleuthero stress resilience blend (125mg). Performs best when cortisol is managed and sleep is restored.

BlackAshwagandhaβ„’

Stress & Cortisol Control Complex

The daytime cortisol layer Β· Take morning, every day

The upstream solution. 650mg certified organic Ashwagandha root plus 5mg organic Black Pepper for absorption. Supports the HPA axis β€” the hormonal system governing how the body produces and recovers from cortisol β€” reducing the chronic elevation that suppresses testosterone and disrupts sleep. Taken in the morning to support the body’s natural cortisol regulation cycle through the day. One capsule. Entirely organic.

NightEdgeβ„’

Deep Recovery & Testosterone Restoration Complex

The overnight recovery layer Β· Take before bed, every night

The night layer that closes the cortisol-testosterone cycle. Melatonin (10mg) for sleep onset. L-Tryptophan, GABA, 5-HTP, and L-Theanine for deep sleep quality and nervous system calm. Ashwagandha for overnight cortisol clearance β€” the hormonal condition that allows testosterone production during sleep. Lemon Balm, Passion Flower, Valerian, and Chamomile for sleep depth without morning grogginess. The recovery that poor sleep has been preventing.

The daily protocol.

Morning β€” StoneBoneβ„’ + BlackAshwagandhaβ„’

Take 2 tablets of StoneBoneβ„’ and 1 capsule of BlackAshwagandhaβ„’ together in the morning with a full glass of water. Morning is the right time for BlackAshwagandhaβ„’ β€” cortisol naturally peaks in the early morning, and taking Ashwagandha at this time supports the body’s daily cortisol regulation cycle through the day.

Evening β€” NightEdgeβ„’

Take 2 capsules of NightEdgeβ„’ 30–60 minutes before your intended sleep time. This gives the Melatonin and calming botanicals time to work before you lie down. The combination of daytime cortisol management (BlackAshwagandhaβ„’) and overnight recovery support (NightEdgeβ„’) closes the full cortisol-testosterone cycle.

The cortisol-testosterone axis. Why this stack addresses both sides.

The relationship between cortisol and testosterone is not incidental β€” it is direct and well-documented. The HPA (hypothalamic-pituitary-adrenal) axis, which governs cortisol production, and the HPG (hypothalamic-pituitary-gonadal) axis, which governs testosterone production, share upstream regulatory mechanisms. When the HPA axis is chronically activated β€” as it is under sustained stress β€” it directly inhibits the HPG axis, reducing luteinizing hormone (LH) secretion and suppressing testicular testosterone production.

Poor sleep compounds this. Testosterone production occurs primarily during sleep, particularly during slow-wave phases. Cortisol levels naturally drop during deep sleep, allowing testosterone production to proceed. When sleep is shallow or fragmented β€” as chronic stress produces β€” cortisol stays elevated through the night and testosterone production is curtailed.

The Stress-to-Strength Stack addresses the full cycle: daytime cortisol through the HPA axis (BlackAshwagandhaβ„’), overnight sleep quality and cortisol clearance (NightEdgeβ„’), and the performance and drive baseline that both support (StoneBoneβ„’).

BlackAshwagandhaβ„’ β€” HPA Axis and Cortisol Regulation

Ashwagandha (Withania somnifera) is one of the most extensively studied adaptogens for human stress response and cortisol regulation. The primary mechanism is HPA axis modulation β€” supporting the body’s ability to regulate cortisol production and recovery more efficiently under chronic stress. At 650mg of certified organic root per serving, paired with 5mg of Black Pepper extract for bioavailability, BlackAshwagandhaβ„’ delivers a dose within the range of the most cited clinical research. Effects build over 4–8 weeks of consistent daily use.

NightEdgeβ„’ β€” Sleep Architecture and Overnight Testosterone Recovery

NightEdgeβ„’ addresses two simultaneous targets: sleep onset and quality, and overnight cortisol clearance. Melatonin (10mg) supports rapid sleep onset and circadian anchoring. L-Tryptophan and 5-HTP support serotonin-melatonin production. GABA and L-Theanine reduce nervous system hyperarousal β€” the activated stress state that prevents deep sleep entry. Ashwagandha (in the blend) supports overnight HPA axis recovery and cortisol clearance during sleep β€” the hormonal condition that allows slow-wave and REM phases to proceed and testosterone production to occur.

StoneBoneβ„’ β€” Performance on a Restored Foundation

StoneBoneβ„’ performs best when the cortisol suppression it’s working against has been reduced. Longjack (400mg) for libido and testosterone support, L-Arginine (250mg) for nitric oxide and blood flow, Maca Root (250mg) for drive and stamina, and the Ginseng-Eleuthero blend (125mg) for stress resilience. When cortisol is managed by BlackAshwagandhaβ„’ and sleep is restored by NightEdgeβ„’, StoneBoneβ„’ is no longer fighting a hormonal environment that is actively working against it.

Stress-to-Strength Stack β€” daily protocol.

The Stress-to-Strength Stack runs a day-and-night protocol: morning formulas address the daytime cortisol load, the night formula closes the overnight recovery loop. Together they cover the full 24-hour cortisol-testosterone cycle that chronic stress disrupts.

Morning β€” StoneBoneβ„’ + BlackAshwagandhaβ„’

Take 2 tablets of StoneBoneβ„’ and 1 capsule of BlackAshwagandhaβ„’ together with a full glass of water. Morning is optimal for BlackAshwagandhaβ„’ β€” cortisol peaks in the early morning and Ashwagandha taken at this time supports regulation through the day. With food is fine. Do not exceed stated doses.

Before bed β€” NightEdgeβ„’

Take 2 capsules of NightEdgeβ„’ 30–60 minutes before your intended sleep time with a full glass of water. Reduce screen exposure and avoid alcohol in the 30–60 minutes before taking β€” both reduce NightEdgeβ„’ effectiveness. Do not operate heavy machinery or drive after taking NightEdgeβ„’.

If 10mg of Melatonin feels too strong, start with 1 capsule (5mg equivalent) and adjust. Most men find the full 2-capsule dose works well with a full 7–8 hour sleep window.

For best results across the full stack
  • Take consistently every day β€” cortisol regulation and sleep improvement both build cumulatively
  • Give BlackAshwagandhaβ„’ the full 4–8 weeks β€” the HPA axis adaptation is gradual
  • Avoid alcohol, especially at night β€” it elevates cortisol and disrupts the deep sleep NightEdgeβ„’ is supporting
  • The sleep improvement typically comes first (week 1–2), cortisol management second (week 2–4), and drive recovery third (week 3–6)

Medical disclaimer β€” please read carefully.

Your questions, answered.

Why BlackAshwagandhaβ„’ in the morning and NightEdgeβ„’ at night?

Cortisol follows a daily rhythm and is naturally highest around the start of the day.

BlackAshwagandhaβ„’ is taken in the morning to support the body’s daytime stress and cortisol response. NightEdgeβ„’ is taken before bed to support sleep and overnight recovery.

One works with the day. The other works with the night.

How long until I notice a difference?

The stack is built for consistency, not an instant hit.

Sleep and evening recovery are often the first areas men notice. Stress response and daytime energy generally take longer to build, with drive becoming more noticeable as the underlying baseline improves.

The timeline above shows the progression the protocol is designed around. Individual results vary.

Does NightEdgeβ„’ interact with antidepressants, SSRIs, or other medications?

Yes.

NightEdgeβ„’ contains St. John’s Wort (Hypericum perforatum), which has well-documented interactions with many prescription medications, including:

  • SSRIs and other antidepressants β€” including risk of serotonin syndrome
  • Blood thinners, including warfarin
  • Oral contraceptives
  • HIV medications/antiretrovirals
  • Cyclosporine and other immunosuppressants
  • Some heart medications

If you take any prescription medication, consult your healthcare provider before using NightEdgeβ„’ or starting this stack.

See the full Marco’s Grounds medical disclaimer for additional information: Marco’s Grounds medical disclaimer

Does BlackAshwagandhaβ„’ interact with any medications?

Ashwagandha may interact with thyroid medications and immunosuppressants.

If either applies to you, consult your healthcare provider before use.

Is 10 mg of Melatonin in NightEdgeβ„’ safe?

10 mg is at the higher end of commonly used doses but is within the range used in clinical contexts.

Most men find the full dose works well when taken 30–60 minutes before a full 7–8 hour sleep window. If it feels too strong, start with 1 capsuleβ€”the 5 mg equivalentβ€”and adjust from there.

Can I take all three formulas at once?

No need.

Take StoneBoneβ„’ and BlackAshwagandhaβ„’ together in the morning.

Take NightEdgeβ„’ 30–60 minutes before bed.

NightEdgeβ„’ is a sleep formula and should not be taken in the morning.

What if it doesn’t work for me? β€” 30-day money-back guarantee.

Your first order of each product in the stack is covered by Marco’s Grounds’ 30-day money-back guarantee.

If an individual formula does not deliver a meaningful improvement within 30 days, contact Marco’s Grounds for a refund on that product.
