I've done Indigo several times. I would not do it if you are just getting back into. The frequency of the main lifts will kill you. If you really wanted to do. I always do a primer phase before Indigo were I only do the frequency lifts and my third day, the lats and arms, I do as written. Don't do any of the spec workouts. You do not need them and they are a waste of time. After 4 weeks of getting used to the main lifts again. Then add the pump stuff afterward. Also with this way you don't really need to other supplements as much, save for the 4 weeks and get Indigo-3G after the primer phase.
