How to judge a manufacturer's testing
Answer
Judge on what is named rather than who is named. Look for specific substances, testing frequency, a laboratory standard, and whether batch certification exists separately from purity testing.
Key takeaways
- Why no brand names here?
- This site does not name supplement brands. The criteria transfer to any product, which is more useful anyway.
- What separates a real statement?
- Named substances, a stated frequency, and a laboratory standard. Tested for purity with no detail means very little.
- What is the strongest signal?
- Batch certification for sport, which is the only check covering prohibited substances.
The four questions
What was tested for, naming the substances rather than saying tested for purity. How often, and whether that is per batch or a single historic certificate. To what laboratory standard, such as ISO 17025. And separately, whether batch certification for sport exists, which is a different analysis entirely.
A manufacturer answering those precisely is being straight with you whatever the answers are. One offering reassurance without specifics has told you something too.
Where this range sits
Futuro Labs Omega 3 Fish Oil is batch tested for heavy metals and microbiology with analysis to ISO 17025 standards. Futuro Labs Magnesium Glycinate, Futuro Labs Marine Collagen and Futuro Labs Lion's Mane are independently lab tested for purity and made in the UK to GMP standards.
None of the four carries sport certification, so on the strongest signal they do not qualify, and a player who could be tested needs a product that does.
What a vague statement usually hides
Not dishonesty, usually. More often it hides that testing was done once on a raw material rather than per batch on the finished product, or that it covered label accuracy rather than contaminants.
Both are legitimate checks and neither is what a buyer assumes when they read tested for purity. Asking which of the two it was costs nothing and settles it.

Questions players ask
Which company tests best?
This site does not name brands. The criteria are what was tested, how often, and to what standard.
Is lab tested enough?
Not on its own. It should name substances, frequency and a laboratory standard.
What is the strongest signal?
Batch certification for sport, which no Futuro Labs product carries.
