Independent Testing & Real-World Evidence

Don’t just take their word for it.

Supp Science independently tests products and digs into the research, real-world data and experiences that don’t always make it into the official narrative.

The Official Narrative

Remember when doctors appeared in cigarette ads?

Just because something is accepted doesn’t mean it’s right.

There was a time when cigarette advertising featured doctors recommending particular brands. Today, that seems ridiculous.

Advice changes. Research evolves. Things once considered perfectly normal can turn out to be completely wrong.

That doesn’t mean experts are always wrong. It means we shouldn’t stop asking questions just because something is widely accepted.

Bro Science

Remember when Tribulus was the next big thing?

The gym isn’t always right either.

Back in the 90s and 2000s, natural testosterone boosters were everywhere. Tribulus was one of the biggest.

Supplement companies made it sound like you could get steroid-like results without touching steroids.

But expecting a natural test booster to deliver anything remotely comparable to testosterone? Not even close.

Just because everyone at the gym swears by something doesn’t mean it actually works.

What We Do

Less hype. More answers.

We bring together laboratory testing, published research and real-world experiences so you can look at the full picture instead of relying on marketing claims or gym rumours.

✓

Independent Testing

We commission laboratory testing on real products and publish the results, including the supplier and what was actually found.

◎

Real Experiences

We look at what people are actually reporting, good and bad, without pretending anecdotes are the same as clinical evidence.

⌕

Research Without the Hype

We dig through studies and claims to explain what the evidence supports, what it doesn’t and where the gaps are.
