Congrats on your gains! You don't need to go full decon necessarily; I recently posted an article explaining how to both decondition & cement gains at the same time.
Also, I’ve had my share of ups and downs with PE too. I don’t fully understand all the tissue mechanics behind it, but one thing I’ve noticed is that regressions do happen. They’re more common after an injury, since uncemented gains can slip back, but I’ve also had periods where I just couldn’t hit a measure I’d reached before.
In 2024 I was pumping to 8″ BPEL in the tube (Bathmate,) then after a forced month off due to an injury at the start of 2025, I lost ground and couldn’t get there again... Not until today, 8 months later! Sure, we have setbacks, but the most important thing is just keep going.
Side-note: I have yet to reach 8" BPEL outside the tube (yet).
