How to Inject Hormones

Learn about how to inject hormones and access safer injection supplies.

Here are two new guides to giving yourself intramuscular and subcutaneous hormone injections.

  • Intramuscular injections pamphlet - a guide to giving yourself intramuscular hormone injections by Trans Care BC and BC Centre for Disease Control (BCCDC) Harm Reduction Services.
  • Subcutaneous injections pamphlet - a guide to giving yourself subcutaneous hormone injections by Trans Care BC and BCCDC Harm Reduction Services.
The link below is an external resource designed to help gender diverse individuals and their care providers with hormone injections.

Please note that the dorsogluteal site (i.e. the buttocks) is no longer recommended for intermuscular (IM) injections because of the chance of the needle affecting the sciatic nerve. Instead, many people self-inject into subcutaneous (fat) tissue - it is easier, safer and equally effective. We encourage individuals to speak to their care provider about the injection routes and sites that are best suited for them. If you need help connecting with a knowledgeable care provider, contact Trans Care BC's Health Navigation Team: or 1-866-999-1514.
