I did halo for the first time @ 20mg for 4 weeks, wow.
I have never felt so tight, although I can not confirm my liver values as I did not get blood test fine, I felt fine in general, which does not mean much.
But wow, best AAS i ever took for hardness hands down.
My only .2cents , you should really be below 10-12 % and below to get the full benifit of it.
