About Me
Marcin
United Kingdom
Hi, I am Marcin — a strength training and running enthusiast with years of experience working on my physique and health.
I created MarcinLabs to document a real transformation journey without marketing shortcuts or miracle promises — and to build transparency around independent laboratory testing.
My goal is to share practical knowledge, analytical results and a critical approach to fitness, research and RUO material quality information.
