I suggest trying over 3000 calories a day to see if it makes a difference first.
Liver supplements...one of the best ones is liv 52.
Go to
Liv.52 - Herbal Liver Support
Some use milk thistle but I believe liv 52 is better.
When on cycle get your liver profile from your doctor....with a low dose you probably won't have to worry but best to be safe.
Try upping the calories more and then do your cycle.
