Cementing involves maintaining your routine for a numbers of months after achieving your desired gains. Essentially, you need to overshoot the mark a bit to counter the expected losses.
That being said, I’d also like to point out that everyone is different. Members here have reported loses after stopping PE varying from only 0.1” to everything ever gained. So, I’d say a long term maintain program is the way to go. Maybe jelqing in the shower once a week or something. You can also search for maintance programs.
