Channa Jayasena

Professor Channa Jayasena, a consultant in reproductive endocrinology and andrology at Imperial College London and Hammersmith and St Mary's hospitals, is a leading expert raising concerns about the proliferation of experimental peptides and steroids in the UK. He describes the current situation as a "wild west," warning of potential fatalities due to the unregulated sale and use of these substances. Professor Jayasena is frequently encountering patients who are using these experimental drugs, highlighting the immediate risks associated with their consumption. His expertise is also relevant to discussions around perimenopause, where he, along with other experts, has noted that misinformation on social media can put women at risk of unintended pregnancies, incorrect medication use, and delayed diagnoses. Professor Jayasena's current newsworthiness stems from his vocal warnings about public health risks associated with unregulated substances and the spread of medical misinformation.
