I tested my testosterone level and found it 282. I always feels energyless, anxious, insecure from everyone around and stammer when nervous, don't loose belly fat after lots of workout and controlled diet. Already taking vitamin d and vitamin c tablets with Ashvagandha for 2 month. Is my anxiously and other traits like periodic stammering, feeling insecure, lazy, energyless is due to low testosterone level? What should be treatment for above symptoms? My age is 30, weight 70 kg, body fat 25%, height 167 cm.
