How It Works

See What Actually Works for People Like You

PEERtrainer runs structured experiments where real people test routines, supplements, diets, and devices together - and share honest, measurable outcomes.

Three Simple Steps

1

Find an Experiment

Browse experiments by category, goal, or what interests you. Each one has a clear hypothesis, defined rules, and a set duration so you know exactly what you're signing up for.

2

Join and Follow the Protocol

Once you join, follow the structured protocol - use the product or routine as described, log your daily and weekly updates, and share honest reflections along the way.

3

See the Real Results

When the experiment ends, see run-level outcomes segmented by demographics and goals. Filter by people like you to understand what actually happened - not what someone claims.

What Makes This Different

This isn't a forum, a review site, or an influencer feed. It's structured citizen science with real accountability.

Structured Protocols

Every experiment has clear rules, eligibility criteria, and a measurement plan. No guesswork, no random opinions.

"People Like Me" Filtering

Results are segmented by age, sex, goals, and lifestyle so you can see outcomes for people in your situation.

Transparent Measurement

We show you exactly what we measure and how. Daily check-ins, weekly reflections, and standardized outcome metrics.

Real People, Real Data

No paid reviews or influencer hype. Participants are real community members sharing honest, structured feedback.

What We Measure

Every experiment includes a measurement plan with daily check-ins (adherence, quick metrics) and weekly reflections (subjective outcomes, detailed notes).

Outcomes are always self-reported and presented at the experiment level. We never claim “this works” — we show you what happened to the people who participated, segmented by demographics and goals.

What This Is Not

Not a clinical trial - it's structured citizen science with transparency about methods
Not a review site - participants follow protocols, not just share opinions
Not medical advice - always consult your healthcare provider
Not cherry-picked results - all run data is shown, not just success stories
