You can pulse Bola - same as Epi. However, pulsing won't prevent shutdown - not even with Epi. I'm experimenting with a pulse method now that should prevent shutdown - a two week pulse followed by a two week pause followed by a two week pulse and then end. So it's a one month pulsed cycle spread out over 6 weeks.
I don't expect to see a lot of muscular gain from it - but what I'm really doing is using it as a "cutting" method. A week and a half in and I'm down 5 pounds and leaning out nicely while retaining strength.
