Testosterone patches can be either scrotal or non-scrotal and are also known to be effective in increasing the body’s T-levels. The downside to using this however is that it tends to irritate the skin. Testosterone gels are known to be significantly absorbed by the skin and have a near-instant absorption rate which lasts throughout the day. And there’s also the buccal testosterone which is known to produce even better results than the patches when applied to the gums. The side effects of that however often include bitter taste in the mouth and some irritation to the gums.
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.
