Should I inject testosterone subcutaneously or intramuscularly?
Last updated: January 2026
Quick Answer
Both subcutaneous (SubQ) and intramuscular (IM) injections are effective for TRT. SubQ uses smaller needles (27-30 gauge), is less painful, and may provide more stable absorption. IM injections deliver larger volumes more easily. Most modern TRT clinics now recommend SubQ with insulin syringes for convenience.
