I'm at week 12 on a cycle of 200mg test p eod. I'm planning on doing 16 weeks, but thinking about extended to 18. I don't want to blast and cruise--fully intend to do PCT at the end of this. Question is, what's the longest you can run a test cycle for before you get into problems recovering? I've heard of 16 weeks, but not sure I've seen anyone go longer than that without transitioning into a cruise. I'm 38 and naturally had very high t before my cycle, if that matters.
