Our creatine is third-party lab-tested for purity and accuracy and certified by Labdoor™, meaning every batch is:
- Verified to meet or exceed strict FDA safety guidelines
- Rigorously tested to ensure it is free from heavy metals, microbes, allergens, and other contaminants
- Confirmed to contain exactly what is on the transparent label, with no proprietary blends or hidden ingredients
- Backed by lab testing results that are publicly shared here on our website for your verification
And all of this is verified by independent, accredited laboratories, not our marketing team.
What Is Labdoor™ Certification?
Labdoor™ is a leader in independent analysis of supplements to assess their quality and safety.
They directly and anonymously purchase products from retail channels and utilize FDA-registered laboratories to rigorously test for label accuracy and purity.
For Legion, this certification means we can conclusively verify safety and efficacy for our customers. Specifically, this guarantees that our products:
- Meet or exceed strict FDA safety guidelines
- Are protecting you from dangerously high levels of toxins like lead, arsenic, and cadmium, which are found in some competing supplements
- Are rigorously tested for heavy metals, microbes, allergens, and other contaminants, ensuring they meet the strict purity standards set by the FDA
- Are backed by absolute transparency, as we publicly share these third-party lab testing results directly on our product pages for your verification
In short, Labdoor™’s independent verification is your assurance that you’re putting only the safest, most effective ingredients into your body—guaranteed.
Why Does Third-Party Testing Matter?
For better or worse, the FDA doesn’t review or approve dietary supplements before they hit store shelves. Unlike prescription drugs, supplements can be manufactured and sold without proving to anyone that what’s on the label is actually in the tub.
Therefore, a brand can print “lab-tested” on its packaging without ever analyzing a single batch to an outside lab. The FDA and FTC can step in after the fact to punish offenses, but enforcement is reactive and stretched thin, so by the time a problem is caught, the product has already been on shelves and in your body.
Some brands voluntarily pay for independent testing anyway, but most don’t because it’s expensive and, in some cases, would expose product deficiencies they’d rather keep quiet.
The gap shows.
Independent testing by consumer advocacy organizations has repeatedly found supplements containing less of a key ingredient than advertised, more than listed (which gets dangerous with stimulants), or contaminants like lead, arsenic, and cadmium above FDA safety thresholds.
That’s not a scare tactic—it’s a matter of public record. And it’s why we don’t ask you to take our word for it.
Every batch of our creatine goes to an independent, FDA-registered lab through Labdoor™, a third party that buys products anonymously off retail shelves, the same way you would. Then, they test whether the dose matches the label and whether the product is free of harmful contaminants, then publish the results for anyone to read.
The Bottom Line on Lab Testing
In the supplement industry, if a brand asks you to “just trust us bro,” don’t.
When you see the “Labdoor™ Certified” badge on our creatine, it’s there because it passed rigorous FDA-registered lab tests and has a public paper trail to prove it—not because our designer thought it looked nice on the label.

Why the $199 minimum purchase amount for free shipping?
To quench our piggish lust for grubby profits in the eternal service of the dread lord Mammon?
Kind of. But not really. Because here’s the truth:
Single-item orders are so blasted expensive to ship that we make very little profit on them. And no profits make the bean counters lose their marbles.
But when you order just one more item, it only costs us a few dollars more to ship both of them to you. Add a third item, and it’s just a few more shekels to ship.
And that allows us to make a profit. Which keeps the bean counters happier than a hammer in a nail factory.
So, if it pleases your Grace, we humbly request your mercy and patronage notwithstanding the vexing free shipping minimum.
