You shouldn’t need to do a 70 day long cycle of PCT. If you only used Red Growth for 4 weeks and you were using 1 PCT/day with the Red Growth, then a single 30 day cycle of PCT should be sufficient to properly cycle off and help maintain your gains.
Regarding Red Burner, I would recommend waiting until you are finished with your PCT cycle before beginning Red Burner. While Burner and PCT could be stacked, since you just did a cycle of growth, I think it would be best to give your body a break before jumping into a burner cycle.
1. 30 days of full PCT cycle (3 caps of Red-PCT per day) is good after a Red Growth Cycle.
2. Once you finish your PCT cycle you can begin your Red Burner cycle.
