Yes it is legal but they rather not, incase you have very very low test levels, and if they accept and give you these trt dose, we talking under 100 mg per week. Sure you maybe will get your test levels to the average male levels. but yeah in my case my levels were ”average” before, but somehow i did stuttering even then, now it is almost gone. and yeah i understand i cant be over 3000 ng/dl all around because my body will be taking damage, so will lower dose after some weeks, but that is a price i am willing to pay to be like normal humans who dont stuttering
