Are Peptides Safe? What to Know About Research Peptides
Safety depends on the specific peptide, and most research peptides have not been tested in people. Many have only been studied in cells or animals. Unauthorized products have not been assessed by Health Canada, and their contents may differ from the label.
Safety Depends on the Peptide
The word peptide covers thousands of different molecules. Some are authorized prescription drugs with extensive safety data. Others are research compounds with only laboratory or animal studies behind them. They cannot be grouped together.
What Health Canada Says
Health Canada has warned Canadians not to buy or inject unauthorized peptide drugs sold online. It says these products have not been assessed for safety, efficacy or quality, and may contain too much, too little or none of the stated ingredient.
Quality Is Part of Safety
- Purity and identity: confirmed by HPLC and mass spectrometry. See peptide purity explained
- Lot-matched COAs from an independent laboratory
- No medical claims on the label or website
