Injections and pellets deliver the same hormone by very different routes. Injections give you dose control and cheap medication in exchange for a needle every few days. Pellets give you months of hands-off therapy in exchange for a minor procedure and a dose you cannot change once it is implanted.
Cypionate or enanthate injected intramuscularly or subcutaneously, typically once or twice weekly. Splitting the dose smooths peaks and troughs. If a side effect appears, the dose can be changed the same week.
Compressed pellets are implanted under the skin of the upper hip through a small incision, releasing testosterone over three to six months. Levels often peak in the first weeks and taper toward the end of the cycle. Removal is possible but unpleasant, so dosing errors persist for months.
Choose injections while you are still finding the right dose, if you have any history of elevated hematocrit or estradiol, or if cost matters. Injections are also the safer choice if there is any chance you will want to stop therapy.
Choose pellets once you are stable on a known dose, tolerate therapy well, and value not thinking about treatment for months at a time. Ask the clinic how they dose pellets against your prior injection protocol rather than a generic chart.
Not simultaneously, but many patients start on injections to establish the right dose and switch to pellets for maintenance. Some switch back to injections if a pellet cycle produces levels that are too high or too low.
Compare clinics by measured testosterone response, not by delivery-method marketing.
