Biohacking Kompakt in English
Biohacking Kompakt is a fact check of supplements, peptides and biohacking practices. All 460 topic pages, 59 tips, 15 comparisons and 18 question pages are available in English: first what holds up, then where the data stop – each with a BK-Score and the underlying sources. Below is a selection; the full lists are under All topics, Tips, Comparisons, Questions and Glossary. All sources are in the study database, and the Biohacking Report 2026 sums up all 494 entries.
New: the podcast in English. Paul and Paula now also talk in English, with a new episode every week: Biohacking Kompakt – English Edition on Spotify. The daily podcast stays in German; its episode pages are summarised in English.
The score rates the state of knowledge, not the substance. Information only, not medical advice.
