I will try to make a long story short for everyone's convenience. I've been on TRT for about 5 years. Before starting TRT my level was 1.3 ng/ml. After a few months of trial and error the doctor and I finally agreed that a dosage of 1.5ml of 200 mg/ml testosterone cypionate per week, worked the best for me and that's where I stayed for 4 1/2 years with regular blood tests and Dr. exams to keep and eye on everything. 6 months ago I moved outside of the US and have had a hard time finding a doctor and legitimate source of testosterone after my US supply ran out. So far I have kept things going though a reputable Dr., lab and pharmacy. The first Dr. said the only testosterone available was Aveed. The price is higher than in England but cheaper than the US. After about 2 weeks I noticed that I was tired all the time and my libido was down again. Seeing as how this was supposed to last 2-3 months per shot, I wasn't sure what to think at first. A trip to the lab showed my testosterone at 2.5 ng/ml and my estradiol at 67 pg/ml. Not wanting to spend another fairly large sum of money on something that didn't seem to work for me, I changed doctors. This doctor claimed that Aveed and Sustnon 250 are the only approved types of testosterone for sale in this county. I took one shot of Sustnon 250 at the doctors office and a follow up shot at 1 week instead of the 2 weeks that the Dr. recommended because I was still feeling terrible. Another week has passed and I still don't feel any better. 0 improvement. I had assumed that since there were some fast acting esters in Suston that I would at least see some improvement after 2 doses. I visited the lab today and should my results back tomorrow but I wanted to go ahead and start this thread. I have a pretty good feeling that my labs will be off. I took the time to speak with a couple of pharmacy managers and the story that doctors told about Aveed and Sustnon seem to be the truth. Any other type of testosterone is black market here. There are plenty of types available on that market but I really didn't want to go down that road but I am starting to feel boxed in by the lack of a legit product that will work for me. Does this problem sound familiar? Is is common to respond to one type of testosterone very well but not respond well to others? I always thought test was test. I will post my new lab results tomorrow but I am interested in any opinions in the mean time. Thanks in advance for any help.
