Running vs cycling BPC — anyone actually stop for long enough to tell?

Observation: most people I talk to who 'cycle' BPC are actually off for 1-2 weeks before restarting because they feel worse or because an old injury whispers. That's not a cycle, that's a dose holiday.

Has anyone been completely off BPC for 2+ months after a long run? What happened? Did the benefits persist, fade slowly, or crash?

I'm asking because I want to know if the cycling guidance is actually giving us any observational signal on long-term vs short-term effects.

Achilles, ran 8 weeks, stopped for 4 months. Benefit persisted. Didn't slide back. This was after a full rehab block though, so I attribute the durability to the rehab and the BPC to the window that let me do the rehab.

Medial epi, 6 weeks on, 3 months off. Pain came back at about month 2 off but at a much lower intensity than before the cycle. Re-ran 4 weeks and it dropped again. So partial durability, not full.

Gut protocol, 6 weeks on, 8 weeks off. Symptoms crept back over weeks 6-8. Not crashed, just drifting. Did a second cycle and the effect was similar. Looks like maintenance territory for me.

Interesting split. Durable for tendons, drifty for gut. That tracks with 'acute healing is a one-time thing, inflammatory gut is an ongoing process.'

ran it 10 weeks for a shoulder impingement, completely stopped for 5 months. took like 6 weeks for the creeping ache to come back but it never got as bad as before i started, stayed like 60% of baseline discomfort. think the tendon_theory guy nailed it though, structural stuff seems to actually stick around whereas inflammation is just kind of waiting for you to feed it again. haven't gone back on it yet but probs will do a short 4 week refresher this winter just to flatten it out before getting back into throwing.
