RE News Investigation: AI, Peptides, and the Growing Information Gap

A recent Re: News investigation explores the rapid rise of illegal peptide use in New Zealand and the increasing reliance on AI chatbots like ChatGPT for guidance on how to use these substances. The report highlights how social media, online vendors, and AI-generated advice are contributing to a fast-growing underground peptide market with significant health and legal risks.

Key Findings

• AI as a substitute for medical advice:

  
  

  Users interviewed in the investigation described turning to AI chatbots for instructions on peptide dosing, mixing, and injection protocols because they felt uncomfortable speaking to healthcare professionals.

• Peptide popularity is rapidly increasing:

  
  

  Google Trends data and feedback from the NZ Drug Foundation indicate a significant rise in public interest and use of peptides since early 2025.

• Social media fuels accessibility:

  
  

  Platforms like TikTok and Instagram are being used to market peptides through influencers, “stack” recommendations, and direct-message sales tactics, despite the products often being illegal to sell or possess without a prescription.

• Illegal peptide sales are widespread:

  
  

  The investigation demonstrated how easily peptides could be purchased locally, including same-day delivery in residential neighborhoods. Some vendors also supplied sterile water and injection equipment.

• Major health and safety concerns:

  
  

  Experts warn that many synthetic peptides lack large-scale clinical testing, and risks include contamination, improper dosing, infections, and unsafe injection practices. Drug testing services also struggle to conclusively identify many peptide substances.

• Calls for harm reduction rather than stigma:

  
  

  Health experts and harm reduction advocates argue that stricter regulation alone will not stop peptide use. Instead, they emphasize education, safer injection practices, drug-checking services, and better clinician engagement to reduce harm.

Overall Takeaway

The Re: News investigation reveals a growing public health issue where AI tools, social media, and limited medical guidance are intersecting to normalize and accelerate peptide use. While AI can provide quick information, experts caution that it cannot replace professional medical oversight, especially for substances with limited scientific research and serious safety risks.
