The sust I am on now is 300 mg and it has a lot of BA in it as well. The reason I asked about the t-400 was because I wanted to switch because of the severe pain for 3-5 days, knotting at injection site, night sweats, chills, that I have been experiencing with sust. I did cut the sust with bold the other day and did my first delt inject and so far it has been more tolerable than the glute shots. My last glut shot was 6 days ago and there is still a knot there and pain. However, it is not red or hot to the touch.
