I agree with TG in getting blood work. There could be numerous reasons why you don’t have a sex drive or just one small issue. Or you’re really stressed and don’t know it.
If all the numbers are okay maybe try different medications, Test Gels or creams. Some TRT docs will do a low dose of Test Cream with a low dose Test shot.
Make sure they check your DHEA levels, prolactin, thyroid.
I know with myself, same dosage every week, some weeks no sex drive, then a few weeks of feeling amazing and having a awesome sex drive.
