The Science

Real Ingredients. Real Science.

Every Headstrong formula is built on ingredients chosen for what the research actually supports — at doses you can read on the label. No proprietary blends, no fairy dust, nothing we can't point to a study for.

How We Formulate

Four Rules We Don't Break

The same standards our athletes are held to, applied to what goes in the tub.

01

No Proprietary Blends

Every ingredient and every dose is printed on the label. If we won't tell you how much is in there, it shouldn't be in there.

02

Doses That Match The Research

Ingredients are included at amounts consistent with the studies behind them — not sprinkled in at a fraction of the dose so they can appear on a label.

03

Certified For Competition

Every formula is NSF Certified for Sport, so athletes competing under anti-doping rules can take it without second-guessing the batch.

04

Built With Athletes

Formulas are developed and pressure-tested with 500+ competitive and professional athletes who use them through real training and competition schedules.

Testing & Certification

Tested Like It Matters

Our athletes compete under anti-doping rules. That sets the bar for how every batch is made and tested.

NSF Certified For Sport Every formula is certified against the NSF banned-substance list, batch by batch. This is the standard most professional leagues and the NCAA point their athletes toward.
Third-Party Tested Identity, potency and purity are verified by independent labs — not self-reported.
Made In The USA Manufactured in cGMP-compliant facilities under documented quality controls.
Clean Label No artificial stimulant loading, no undisclosed blends, no ingredients we can't justify.
