Which is more effective? testosterone injection or androgel?

T gel vs injection: Both effective, injection more reliable but gel can be applied daily.

Gel vs injection: Testosterone replacement therapy, or trt, can be done with shots (typically administered every 2-3 weeks) or a daily application of a gel or cream. Both methods are fda-approved. Shots increase t levels rapidly and taper off slowly until the next shot. The topical method, in my opinion, is superior in that it mimics more closely how t is secreted naturally by your body.
