Everything we know and can show about research peptides: basics, analytics, legal status and the tools we use ourselves. Every page separates what is established from what remains open.

Amino acid building blocks, the peptide bond, the difference from proteins and why length and order determine properties.

The questions laboratories answer with peptides, from receptor signalling to tissue models, and where the line to human use runs.

What HPLC, mass spectrometry and content measurement show, how a lab report is built and how to verify it at the laboratory.

Why the intended use decides, what medicines and anti-doping rules mean, and the rules we sell by.
