Welcome to the forum. I'm a newbie to the forum myself but have been on TRT for 13 years. Sorry to hear about the past year being so terrible. I'm not surprised you had problems on 200 mg Cyp once every 10 days. A protocol like that doesn't work for very many people, if any. I'll bet you had an emotional rollercoaster on 200 mg every 10 days. If you could post your complete labs it would give others on the forum, with a great deal of experience, a better chance to try and help you. Do you have labs that would include total and free testosterone, estradiol sensitive (the LC/MS/MS assay), SHBG, PSA, and a complete thyroid panel? Finding out what your SHBG is will go a long way in these gentlemen on the forum being able to help you. It will help determine what would be your best protocol. If I were you I would not change anything yet. 30 mg three times a week is probably better than one large injection of 100 mg unless your SHBG is very high. Sit tight, post the labs, and these guys will help you. Best wishes
