Health Canada has issued safety warnings about unauthorized injectable peptide drugs promoted online for anti-aging, weight loss, bodybuilding, athletic performance, injury recovery, sleep, focus, and wellness.

Key Warning Points

Health Canada's advisory highlights:

• Unauthorized injectable peptides have not been assessed for safety, efficacy, or quality
• Products may be contaminated, incorrectly labeled, or improperly manufactured
• Injectable products carry specific risks including infection, allergic reactions, and organ damage
• Products marketed as "research use only" or "not for human consumption" may still be marketed to consumers with implied use instructions

Products of Concern

The warning encompasses a broad range of peptide types sold online without authorization, including but not limited to growth hormone-releasing peptides, melanocyte-stimulating hormone analogs, and tissue-repair peptides.

Regulatory Context

In Canada, drugs require authorization (Drug Identification Number or DIN) before they can be legally sold. Products without a DIN that make health claims or are presented as drugs are unauthorized and illegal to sell for human use.

Consumer Guidance

Health Canada advises consumers to:

• Consult healthcare providers before using any peptide product
• Verify that products have a DIN
• Report adverse reactions to Health Canada
• Be skeptical of health claims made by online sellers
