Both intramuscular (IM) and subcutaneous (SubQ) injections can be effective for TRT, and the best choice depends on personal preference, absorption rate, and side effect management.
Intramuscular injections are the traditional method, delivering testosterone into the muscle (usually the glutes). This provides rapid absorption and stable levels but may cause more injection site soreness and require larger needles.
Subcutaneous injections involve injecting into the fat layer (usually around the abdomen or thighs) with a smaller needle. Many men find SubQ injections less painful, easier to administer, and better for reducing post-injection pain or lumps. Some also report fewer estrogen spikes and smoother hormone levels, but absorption may vary between individuals.
Both methods are effective, and the choice comes down to what works best for you. If IM injections cause discomfort or side effects, switching to SubQ is worth trying. For more details, see TRT Injection Techniques: IM vs. SubQ Explained.
