Daniel Murphy's mental health spiralled after he took missold drugs which had been mixed with steroids.

Daniel Murphy went from being a loving husband to a man who believed his family wanted to kill him Daniel Murphy thought he was taking a safe and tested dietary supplement that would help him put on muscle in the gym. But over the following two years, his mental health spiralled to such a degree he ended up in a state of psychosis in which he believed his wife was trying to steal his business and his mother-in-law was going to kill him. Unknown to Daniel, the daily pills he had been taking had been mixed with testosterone. The 32-year-old is one of 54,000 consumers listed in a case against a multimillion-pound peptide company based in the US, which sold its products around the world. The owner of Paradigm Peptides, Matthew Kawa, was jailed for five years and 10 months on Thursday after he admitted deliberately selling unapproved medicines, trying to deceive people about what they were and illegally bringing the products into the country. His sister, Jennifer Stechkober, who also pleaded guilty to selling unapproved medicines, was sent to prison for a year and four months. Both admitted they had lied about where the pills were sourced, their purity and their company's testing procedures. Despite claiming the supplements were manufactured in the US, they were actually imported from China, India and several other countries. The pair also faked certificates of analysis, the documents that prove the safety and quality of a product.
