I remember I started out with 20-25mg ED of tren ace. And I got good fat loss and hardness. Although hardness could have been from proviron. With such low doses, prolactine, T3 and other sides won’t be an issue, but don’t expect any anabolism. Although I have friends that use 250mg tren a week, and don’t get any fat burn, neither anabolism, its very diet-dependant at such doses. But you really start feeling tren at 40mg ED.
