DO YOU FEEL LIKE A SHADOW OF YOUR FORMER SELF?
After 30, testosterone levels drop by roughly 1% per year. By the time most men notice something is wrong, they've already lost years of energy, strength, and drive — and they've wasted hundreds of euros on supplements that may have done nothing.
Sound familiar?
The problem isn't that supplements don't work.
The problem is that nobody has ever tested them properly — on real men, with real lab results, over a real 30-day period. Until now.
HOW THE STUDY WORKS
Six steps. Thirty days. Real lab data on what your body actually responds to.
01
ORDER THE STUDY KIT
Purchase the 30-Day Crowd Science Study (€119). This includes your 3 certified testosterone tests, your study protocol, and your participant ID.
02
CHOOSE YOUR SUPPLEMENT
Select one testosterone supplement from our curated list of 25+ options — or bring your own. You purchase this separately. This is the product you will test.
03
TAKE YOUR BASELINE TEST
On Day 1, take your first certified testosterone test. This is your starting point — your personal baseline before the supplement.
04
START YOUR 30-DAY PROTOCOL
Take your supplement daily as directed. No other changes to your routine. The study isolates the supplement's effect on your testosterone levels.
05
TEST AT DAY 15 & DAY 30
Your second test at Day 7 and third test at Day 30 capture how your testosterone responds over time. Three data points. Real lab results.
06

Get your personal report showing your testosterone trajectory. Your anonymised data contributes to the collective study — helping 1,250 men find what actually works.
