I think this approach is fine. I must say having been doing this for years, treating hundreds and thousands of men I have been underwhelmed with the results with topicals. Injections can cause peaks and valley and I have many younger men inject twice a week that smooths out the peaks and valleys. I think it is appropriate to follow the advice of your primary doctor and endocrinologist. I have just seen too many men spend months or years with gels with sub optimal results. Many men are diagnosed with depression and are not really depressed (I have no idea if this applies to you), but the presumed depression is base dupon low T.
My recommendation would be to pursue this but if a few months pass and results are modest consider another approach. Pellets are one approach to have smooth levels of T and are placed every 4 months.
Health problems. Lots of things that can go wrong here but I wont bother to go into too much detail because you have heard it all before. These problems are very dosage dependent and drug dependent. Enlargement of the heart is probably the biggest problem. Although enlarging your heart sounds like a good thing, its very, very bad and is what leads to heart attacks in young bodybuilders. Damaging your kidneys and liver is another relatively common problem as the body works overtime to filter out stuff that it doesnt want. Then there is the problem with natural testosterone production being shut down.
Again, a great question for your doctor!! Discuss this with them. One very good option is always simply not to do it. You are the best one to weigh the pros and cons that your doctor lays out for you and decide what is the right decision for you. One thing that people often fail to realize is that the normal range for testosterone is that – a NORMAL RANGE. That means that readings anywhere in that range are NORMAL. If you are on the “low side of normal” – that is NORMAL. Another thing to realize is that doctors to not treat test results, they treat symptoms. Just because your testosterone comes in at 200 does not necessarily mean you need TRT! See also the below question.
