We regularly update content with the latest publications and clinical trial results from peer-reviewed journals.
A short introduction to peptides and how to read our reviews.
Peptides are short chains of amino acids, the same building blocks that proteins are made of. The body makes many of them itself, for example insulin and oxytocin. They work as signals: they tell cells when to feel full or how to heal a wound. Researchers also make synthetic peptides that mimic these signals.
Our reviews are written mainly in Polish. Each Polish review opens with a short summary called “W skrócie” (in brief). Every finding in it is marked as coming from studies in people, in animals or in cells, and has a number that links to the publication in the bibliography. The study details are further down, in the scientific part.
They work differently. Anabolic steroids are derivatives of testosterone: they enter the cell and bind to a receptor inside it. Peptides usually bind to a receptor on the surface of the cell and set off a specific signal, such as the feeling of fullness or the release of growth hormone. We describe the safety of each peptide separately, in its own review.
With whatever interests you. The Polish reviews cover healing (BPC-157, TB-500 and GHK-Cu), body weight (semaglutide, tirzepatide and retatrutide), stress, memory and sleep (Selank, Semax and DSIP) and growth hormone (CJC-1295 with ipamorelin, and tesamorelin). The English reviews are listed under Articles.
