ain't no fuckin around with the liver...its not like ur testes were you can bring them back...you can get permanent damage from orals...
Always make sure you take within a controlled and realistic dosage and consume liver protection (rALA, NAC, Milk Thisle, Cranberry)
Actually, even if your liver is 75% dead, it can still repair itself.
The one organ to really watch out for when using AAS is the kidneys. (BUN and creatinine)
