Cycling sermorelin, on/off protocols discussion

Curious how people structure cycles. I've seen a few approaches: continuous daily use with periodic bloodwork, 5-days-on-2-off weekly schedules, and longer blocks like 12 weeks on followed by a few weeks off.

The reasoning for cycling I usually hear is preserving receptor sensitivity, though I'm not sure how strong the evidence is. What does your provider have you doing, and what's the rationale they gave you?
