The questions we get most often, answered straight.
Including the ones the industry usually avoids. Jump to any question - or scroll the list.
Is this a natural Viagra?+
No - and be suspicious of anything that claims to be. The pill forces the pathway on a timer. Flow feeds the pathway daily so it can work on its own. Different logic, different experience, no prescription.
How fast will I feel something?+
Weeks, not hours. Weeks 1-2: warmth, training pumps, mornings. Weeks 3-6: reliability. Weeks 8-12: the unplanned moment. Anyone promising tonight is selling the story you've already been burned by.
I take blood-pressure or heart medication. Can I take Flow?+
Talk to your doctor first - especially if you take nitrates. That is not legal boilerplate: nitric-oxide precursors and nitrate drugs work in the same lane, and stacking them is a real interaction. Bring the label - every milligram is printed for exactly this reason.
I've tried testosterone boosters. Why would this be different?+
Because they aim at a hormone that, for most men with this pattern, tests normal. Flow aims at the signal that actually runs the event - nitric oxide. Wrong target explains twenty years of your disappointment better than 'you didn't take enough.'
What exactly is in it?+
Three ingredients, every dose printed: L-Citrulline DL-Malate (400 mg), L-Arginine HCl (350 mg), L-Arginine AKG (50 mg) - plus a vegetable capsule and brown rice flour. Nothing else. Naturally occurring amino acids you can also get from food.
How does the subscription work?+
The price shown is the price charged. You get an email before every shipment. Pause or cancel anytime after the minimum commitment - two clicks, from your account page. No retention specialist, no phone maze, no fine print. Price locked as long as you stay.
What shows up at my door - and on my statement?+
A plain box. A neutral name ('HL Fulfillment') on the label and on your card statement. Nothing that needs explaining to anyone.
What if it does nothing for me?+
Your first month is the test, and it's refundable in full - every dollar, even on an empty bottle, one email. The early signs (training warmth, mornings, fewer coin-flip nights) show up inside that window; if they don't, you're out nothing. Full detail on the Guarantee page.
Do I need to cycle off?+
No. Flow is a daily-feed mechanism, not a stimulant. The whole point is a steady supply of the amino acids your body already uses to build nitric oxide. Consistency is the mechanism.
Can I take Flow with pre-workout, creatine, or a multivitamin?+
Yes for creatine and multivitamins. For pre-workouts, check that yours doesn't already contain large doses of L-citrulline or L-arginine - if it does, you don't need Flow on training days, just on your rest days. There's no benefit to doubling up.
Is it manufactured in the US?+
Yes. Flow is made in a cGMP-certified US facility. Every batch is third-party tested for identity, potency, heavy metals, and microbial contaminants. That testing is why we can print every milligram - the certificate has to match the label.
