I do no think that halo is good for pulsing. The pulsing method is usually applied to stuff that contains harsh sides.
Halo is very slow, very very slow acting. If ran straight, the gains will usually appear around the 3rd to 4th week, and even in pct.
1st dose: morning
2nd pose: pre or post
That is what I would do, but might wait and compare to what others would have done.
