From what I understand, blast & cruise means you're on for life, just like when you join a prison gang, it's for life. The blast phase allows you to use multiple compounds at higher doses. For example, you can run 500-750mg Test E, 400mg Tren E weeks for 12 weeks. You can use Dbol or Var at the beginning or end of your cycle depending on your goals. The cruise phase would require you to use 250mg of Test E for 8-12 weeks and the cycle repeats itself. You can add other exotic drugs likeGH, Slin, DNP, or T3 along the way. I personally wouldn't bother with HCG if I was doing this.
