Doubling on both of the stacks in my opinion would be very harsh on the liver. Any Andro supps I've used I get a lot of back pumps, shins, and some mild acne. I would recommend on stack at a time. Bulk then cut. If this is your first time on pro hormones I would start with something mild and see how you respond. But I'm not a Dr, just gone through research and trial and error. Good luck. Keep me posted.
