FAQ

An independent lab, not us and not the manufacturer, verifies what is in the product before it ships. It confirms that the ingredients on the label are the ingredients in the container and at the amounts stated.

GMP stands for Good Manufacturing Practices, the FDA's manufacturing standard for dietary supplements. It governs facility cleanliness, equipment, staff training, batch records, and testing procedures. Our supplements are produced in facilities that meet or exceed those standards.

No dietary supplement is FDA approved, including ours. The FDA regulates supplements as food rather than as drugs, which means the manufacturer is responsible for safety and label accuracy rather than seeking pre-market approval. That is exactly why third-party testing and GMP-compliant manufacturing matter. These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease.

A Stack is a curated set of products built around one goal, priced 17% below buying the same items separately. Each Stack page lists exactly what is inside and what each item supports. Bundle pricing already reflects the discount, so it cannot be combined with discount codes.

A 30-day money-back guarantee. If a product is not right for you, contact us within 30 days of delivery. Full terms are on our Refund Policy page.

Yes, and that is the idea behind the Stacks, which are built to be taken together. If you take prescription medication, are pregnant or nursing, or manage an ongoing health condition, talk with your healthcare practitioner before combining supplements.

Creatine plays a role in energy production inside muscle cells. It supports muscle performance when combined with exercise, supports lean muscle mass, supports cellular energy production, and supports brain function. Dissolve one level scoop in 8 oz of water or another beverage once daily. It can be taken about 30 minutes before exercise or immediately after.

Nitric oxide is a signaling molecule your body makes from the amino acid L-arginine. It helps blood vessels relax and open. Sero-NOX is an effervescent orange drink mix delivering 2 g of L-arginine and 500 mg of L-citrulline, plus quercetin, vitamin C, folate, and mixed tocopherols. It supports healthy blood flow and oxygen delivery to peripheral tissues, supports healthy dilation of blood vessels, and supports lean body mass and athletic performance. Do not use Sero-NOX if you have low blood pressure.

L-citrulline passes through the intestinal wall easily and is converted to L-arginine in the kidney. Oral L-citrulline has been shown to increase the amount of L-arginine available in plasma for nitric oxide synthesis, so pairing the two raises availability more than L-arginine alone.

Both are nitric oxide precursors. Sero-NOX is an effervescent powder mixed into water and taken once daily, built around L-arginine and L-citrulline. Sero-NitrO is an extended-release tablet taken in divided doses. Choose the format that fits your routine.

Electrolytes are minerals lost through sweat that your body uses to hold fluid balance. They matter most during long or intense sessions, in heat, and any time you are sweating heavily. Our Electrolyte Sticks are sugar-free, infused with vitamin C, and carry the NSF Certified for Sport designation, which means the product has been tested and does not contain substances banned by major athletic organizations. Dissolve one stick pack in 16 oz of water. Less water than that and it tastes noticeably salty.

Our Electrolyte Sticks carry the NSF Certified for Sport designation, which specifically screens for substances banned by major athletic organizations. Not every product in the line carries that certification, so if you compete in a tested sport, check the individual product page and confirm with your governing body.

It varies by product, so always read the individual label. As an example, Sero-NOX contains no wheat, gluten, yeast, soy protein, animal or dairy products, fish, shellfish, peanuts, tree nuts, egg, artificial colors, artificial sweeteners, or artificial preservatives.

It depends on the product and on you. Some formulas, like electrolytes, are noticeable the same session. Others are built around daily intake over weeks. We do not promise a timeline, and you should be skeptical of any supplement brand that does. Take the product as directed and give it a fair run.

Yes, particularly if you take prescription medication, are pregnant or nursing, are managing a health condition, or are preparing for surgery. Supplements can interact with medication. Bring the label with you so your practitioner can see the full ingredient list.
