I know I’ll be executed for saying this but here it goes:
Jelqing alone does not produce gains. It might produce higher EQ, but it just does not have enough tension/pressure to encourage new growth.
Stretching and pumping I can say 100% worked for me for length gains. Straight pulls, fulcrum stretches, and BTC pulls.
For girth I’ll be honest I haven’t had much luck. I’m just recently returning to PE from a long hiatus. I was having the most success when I was doing clamped squeezes after pumping. I did a modified dry two-handed jelq that I called a superjelq that also seemed to give good expansion as well.
Basically you need to graduate your routine. Doing sets of jelqs for a year expecting gains is like trying to become a powerlifter with 15lb dumbells.
I’m not the wisest person here and there are a ton more experienced that should be able to help you create an actually effective routine.
Good luck!
