I do not recommend self-TRT but if you do it, start with 100mg per week of a long ester test. You will want to pin at least twice per week but the best protocols are every day pinning. This is because your body naturally produces testosterone every day so you want to copy that as close as possible. This will also make a big difference in keeping estrogen where it should be. Do not start your dose too high and do not use an AI in a TRT protocol.
