benifit of low am dose of short half life compunds 4-6hrs is nutrient repartitioning (superdrol clones esp.)= the bomb with AM workouts,natty test already high in the morning, less exposure to the liver. Depending on the length of cycle,nuber of days dosing ect, and knowing your own body, will determine the type pct needed and its dosing. Over dosing pct can cause a host of other issues as well. Im no expert just sharing ifo, hope this helps some.
