It's difficult to say something not knowing your cycle but generally Halo has to be taken the last weeks of a cycle (let's say the last 4). The dose of 25/30 mgs ED would be ok and is better to split it during the day.
Don't use it for too long because can give u some liver problems since it's very strong on it, reduce or don't use other orals or 17-a AS (if u want to stay on the safe side).
After all if u can tolerate it is a fantastic hardening drug and will give u amazing strength.
