My experience with Halo was slightly different from what you asked for. I did 20-25mg/day for about 30 days at the end of a cycle. I took Liv-52 all throughout. I am a lil' embarrassed to say this but I partied and drank during that time too. I didn't get a blood test during the cycle but got one about 6 weeks after cycle ended (end of PCT) and my liver values were all fine. It was just my experience; take it for whatever it is worth. Eeach person's reaction can be different to orals. For instance, I can tolerate anadrol very well but dianabol kills me. Headaches, high BP, just a nasty overall feeling when on d-bol. My advice would be to start Halo as you described and monitor liver values as you go along. Good luck.
