Pellets can be convenient because you don't have to worry about pinning weekly. They also make a lot of profit for doctors but are considered "stone age" by some TRT guru's like Dr. Crisler. If it works for you and you feel good, and your numbers are dialed in then stick with it. Many men find it expensive and tough to get your numbers dialed in and it can be invasive. If you are at 1200 with good free T, estrogen in check, and lipids and H&H within rage I don't see a need to lower your dose unless your H&H starts creeping up or other numbers don't look good. Generally speaking, the higher your TT, the more side effects are possible but its different for every man. Its all about how you feel and what your lab work says. Your estrogen is elevated, was this a standard or sensitive test?
