It's harsh on the liver for sure.
I got in a motorcycle accident, knocked out cold and in the ER they were asking me why my liver values were so high. I was on Halo at the time. I also was on jack3d at the time too, they grilled me if I was on meth...
Since I paid for the test I should get the results and see what my liver values were at. Admittedly, I was not on any liver support supps at the time.
It's a 4 week max kind of oral IMO. Though I dont think winny is any better at durations longer than 4 weeks, the joints just start to hurt so bad in my experience.
The aggression on halo is much better than the tren aggression. Its not more per say, just not that weird pissy no sleep funk feeling that tren has given me.
