LIV 52. , milk thistle, NAC, R-ALA, synthergine, UDCA, Tyler's liver cure.
I take around 3G of milk thistle a day in and off cycle.
Synthergine claims to be proven to reduce liver enzymes while using orals and there are many guys who have posted labs.
Tyler's LC is supposed to be really effective also.
UDCA is effective but only need if enzymes get really high.
In general you can find these very cheap and use them as needed for general health, on cycle, and with orals.
I use some NAC, milk thistle, LIV 52, R-ALA.
