Both are good compounds for an oral cycle. Results are highly dependent on diet, training, pct, and personal goals. If you're on an all out bulk, i'd say around ten lbs. Its all subjective really. Results differ from person to person, but i've always had good runs from halo clones. I've got some RPN havic (epi clone) that i picked up based on all the good reviews.
Straight up, you can't go wrong with either. Eat well, train hard, get some sleep, and you'll enjoy the results.
Hopefully that helps bro.
