Unregulated Peptide Self-Administration Spreads Among Bodybuilders Despite INSERM Warnings and Australian Liver Injury Reports

Thomas, a pseudonym for a French gym-goer, reconstitutes and injects GHK-Cu for skin, Retatrutide for appetite suppression, Selank for anxiety, and BPC-157 for tissue repair. These compounds remain unauthorized in France, so dosing derives from Reddit and Discord forums rather than pharmacokinetic data. The AFP account highlights how steroid users transition to peptides after influencer exposure, creating a daily injection routine without laboratory monitoring.

INSERM stated in 2026 that no large-scale randomized controlled trials have confirmed benefits for these synthetic peptides, while Australia's Therapeutic Goods Administration recorded six acute liver injuries linked to Retatrutide-labeled products by June. Hospitalization reports from multiple countries indicate hepatotoxicity and unknown long-term effects when purity and sterility are uncontrolled. Observational data cannot distinguish compound-specific toxicity from contamination or polypharmacy.

The US advisory panel's recent loosening recommendation, criticized for industry ties during RFK Jr.'s tenure, contrasts with French prohibition and illustrates regulatory fragmentation. Wellness marketing frames peptides as optimization tools, yet omits absence of safety pharmacology and the ethical gap around non-consensual self-experimentation driven by online communities.

Future surveillance must track adverse-event registries and require manufacturers to complete phase-3 trials before any compounding allowance; without such data, incidence of serious harm will remain unquantified.
