How to Inject Hormones

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 (ie: 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, please contact our Care Coordination team at  1-866-999-1514.
