Drive without blood flow is desire without follow-through.

Physical responsiveness β€” the strength, reliability, and sensation of how the body responds β€” is a circulation question as much as a desire question. Nitric oxide is the primary mechanism: it signals the smooth muscle in blood vessels to relax, increasing blood flow to the tissue that needs it.

FlowMaxβ„’ is built around that mechanism. Dual-form L-Arginine at 800mg and dual-form L-Citrulline at 400mg β€” the two primary nitric oxide precursors, each delivered in two forms for broader absorption and more sustained availability. No proprietary blend. Every dose disclosed.

Supports nitric oxide production and healthy vascular dilation
800mg dual-form L-Arginine β€” base and AKG for broader absorption and sustained availability
400mg dual-form L-Citrulline β€” HCL and Malate for enhanced bioavailability
Supports stronger, more reliable physical responsiveness and sensation
Niacin for additional vasodilation and circulation support
Full ingredient transparency β€” no proprietary blend, every dose disclosed

What men say when the physical response finally matches the desire.

More responsive. More vascular. More reliable when it matters.

FlowMaxβ„’ is built for you if:

Physical responsiveness is the specific gap β€” the desire is there, the body doesn't always follow
You want stronger, more reliable blood flow support as part of your daily protocol
Endurance and physical sensation matter as much as desire and drive
You've read the science on nitric oxide and want a formula that takes it seriously
You want full ingredient transparency β€” every dose visible on the label
You're on StoneBoneβ„’ and want the dedicated blood flow layer on top of it

Why the nitric oxide pathway matters for physical performance.

Physical responsiveness β€” erection quality, endurance, sensation, and the reliability of the body's response to desire β€” depends on blood flow to the right tissue at the right time. Nitric oxide (NO) is the primary signaling molecule that makes that happen.

When NO is produced in the endothelium (the inner lining of blood vessels), it triggers the smooth muscle surrounding the vessel to relax β€” widening the vessel and increasing blood flow. This is the mechanism behind pharmaceutical PDE5 inhibitors. It is also the mechanism that natural precursor supplementation supports β€” through a different, non-prescription pathway.

L-Arginine is the direct precursor to nitric oxide via the enzyme nitric oxide synthase. L-Citrulline is converted to L-Arginine in the kidneys and raises plasma L-Arginine levels more efficiently than supplemental L-Arginine alone β€” because it bypasses the gut enzyme (arginase) that breaks down L-Arginine before it reaches systemic circulation. The combination of both is more effective than either alone.

Why two forms of each amino acid.

L-Arginine base + L-Arginine AKG 2:1

L-Arginine base provides direct, immediate L-Arginine availability. L-Arginine AKG (Alpha-Ketoglutarate) is a modified form that is absorbed differently β€” AKG acts as a carrier that improves cellular uptake and supports the Krebs cycle, making it more effective for sustained physical performance. Together they provide both immediate and sustained L-Arginine delivery across the dosing window.

L-Citrulline HCL + L-Citrulline Malate

L-Citrulline HCL is the pure citrulline form β€” it converts to L-Arginine in the kidneys with high efficiency and raises plasma arginine levels more effectively than direct L-Arginine supplementation. L-Citrulline Malate combines citrulline with malic acid β€” the malate component supports ATP production and reduces lactic acid accumulation, adding an endurance and recovery dimension that pure citrulline alone doesn't provide.

How FlowMaxβ„’ fits the system.

FlowMaxβ„’ is the dedicated blood flow layer of the MG system. StoneBoneβ„’ provides the broad foundation β€” libido, stress resilience, and daily performance readiness, including L-Arginine at 250mg. FlowMaxβ„’ adds the focused, higher-dose nitric oxide and circulation protocol on top of that foundation. For men whose specific bottleneck is physical responsiveness and endurance, this is the right additional layer.

The science behind FlowMaxβ„’ β€” every ingredient, every dose.

FlowMaxβ„’ is built around the nitric oxide precursor pathway β€” the most direct natural route to improved blood flow and vascular dilation. Six disclosed ingredients. No hidden doses. Here is exactly what is in each serving and why.

Full ingredient breakdown β€” 6 active ingredients, all disclosed.

L-Arginine (base) 400mg Β· Primary Nitric Oxide Precursor
The direct precursor to nitric oxide via nitric oxide synthase. L-Arginine base provides immediate availability and rapid conversion to NO. At 400mg as the base form, combined with 400mg AKG below, the total L-Arginine delivery is 800mg per serving β€” a meaningful dose in the nitric oxide precursor category.

L-Arginine AKG 2:1 Extract 400mg Β· Extended-Release NO Precursor
L-Arginine Alpha-Ketoglutarate β€” a modified L-Arginine form with improved cellular uptake. AKG supports the Krebs cycle (the cell's primary energy production pathway) and carries arginine into cells more efficiently than the base form. Together with L-Arginine base, it provides both immediate and sustained L-Arginine availability across the dosing window. 800mg total L-Arginine per serving.

L-Citrulline HCL 200mg Β· Highly Bioavailable NO Precursor
L-Citrulline is converted to L-Arginine in the kidneys with greater efficiency than supplemental L-Arginine alone β€” because it bypasses arginase, the gut enzyme that breaks down oral L-Arginine before systemic circulation. This makes L-Citrulline a more reliable route to raising plasma arginine levels than L-Arginine supplementation in isolation. HCL is the pure, maximally bioavailable salt form.

L-Citrulline Malate Extract 200mg Β· Citrulline + Endurance & Recovery
Combines L-Citrulline with Malic Acid (Malate). The malic acid component supports ATP synthesis through the Krebs cycle and reduces lactic acid accumulation during physical exertion β€” adding an endurance and recovery dimension that pure citrulline does not provide. The combination is well-established in sports performance research for physical endurance alongside the blood flow benefits.

Niacin (as Niacin) 15mg NE β€” 94% DV Β· Vasodilation & Circulation
Niacin (Vitamin B3) is a well-established vasodilator. At pharmacological doses it is used clinically for cholesterol management; at nutritional doses such as the 15mg NE in FlowMaxβ„’ it supports peripheral vasodilation and healthy circulation β€” contributing to the formula's broader blood flow mechanism. Niacin at this dose may also cause a mild flush (temporary skin warmth or redness) in some individuals β€” harmless and transient.

Beta Alanine 80mg Β· Endurance & Lactic Acid Buffering
Beta Alanine increases muscle carnosine levels, which buffers lactic acid accumulation during physical exertion β€” supporting endurance and reducing the fatigue that physical performance depends on. At 80mg, this is a supporting endurance dose. Beta Alanine commonly causes a harmless tingling sensation (paresthesia) β€” particularly in the face, hands, and feet β€” that is temporary and not a cause for concern.

Calcium (as Calcium Carbonate) 36mg β€” 3% DV Β· Vascular Smooth Muscle
Calcium plays a role in smooth muscle function and vascular tone. Included as a supporting mineral for the formula's broader cardiovascular and circulation mechanism.

Other Ingredients: Hypromellose (Vegetable Capsule), Vegetable Stearate, Silicon Dioxide.

FlowMaxβ„’ instructions.

FlowMaxβ„’ is designed for consistent daily use. The nitric oxide precursor mechanism builds with consistent supplementation β€” most men notice improved physical responsiveness and endurance within 1–2 weeks of daily use, with the full circulatory effect clearest at 30 days.

Standard dose: 2 capsules once daily

Take with a full glass of water. Morning or early afternoon works best β€” taking FlowMaxβ„’ with a meal can slightly reduce L-Arginine absorption. Avoid taking immediately before bed as the vasodilation effect is better utilized during active hours. Do not exceed 2 capsules per day.

Note on Beta Alanine tingling

FlowMaxβ„’ contains Beta Alanine at 80mg. Beta Alanine commonly causes a harmless tingling sensation (paresthesia) β€” typically in the face, hands, and feet β€” within 15–30 minutes of taking. This is not an allergic reaction and is not cause for concern. It is a normal physiological response to Beta Alanine and fades within 30–60 minutes. If you find it uncomfortable, taking with food reduces the intensity.

For best results
  • Take consistently every day β€” the nitric oxide precursor effect builds with sustained supplementation
  • Pairs with StoneBoneβ„’ β€” FlowMaxβ„’ adds dedicated blood flow focus on top of StoneBone's broader foundation
  • Pairs with BlackHornβ„’ for occasion-specific support β€” FlowMaxβ„’ daily, BlackHornβ„’ before specific moments
  • Stay well hydrated β€” adequate hydration supports nitric oxide production and vascular function

Medical disclaimer.

FlowMaxβ„’ is not intended for individuals under 18, or for pregnant or nursing individuals. If you are managing a cardiovascular condition, taking blood pressure medication, or have specific health concerns, consult your healthcare provider before use. Do not combine with pharmaceutical PDE5 inhibitors without medical guidance.

Most nitric oxide supplements use one form of each amino acid. FlowMaxβ„’ uses two.

Single-form L-Arginine has a known absorption ceiling β€” the gut enzyme arginase breaks it down before it reaches systemic circulation in full. L-Arginine AKG bypasses part of this limitation. L-Citrulline converts to L-Arginine in the kidneys with higher efficiency than supplemental L-Arginine alone. L-Citrulline Malate adds the endurance and recovery dimension. FlowMaxβ„’ uses both forms of each, with every dose disclosed.

Customer Reviews

Overall rating: 4.7 / 5 from 551 reviews.

I’m always reluctant to take anything new or additional vitamins, but I wanted to leave a review based on my experience with the product. I automatically felt much more energized in every aspect. I couldn’t figure out what I was doing different if I had more sleep the night before or what but it was just when I started taking the Stone Bone, I ordered. The stone bone testosterone booster is amazing and also the Black Maca . I’m really happy with the product and also the supplement called Confidall. I appreciate your products and I never leave reviews. I just wanted to say thank you for a great product.
