Anyone getting good gain with pumping only and no jelq?

I’m not a big fan of jelqing and rather do more pumping instead. Has anyone got good gain with a pumping only routine?

Some people have over many years of pumping only. I don’t want to wait that long so I’ve incorporated Supra’s Slammers, into my routine. Pumping alone just takes too long to see lasting results.

Read the pumping 101 routine. It works!

I lucked out and gained an inch from pumping alone. Took about 5 mos. But gains happened faster after I started incorporating manual exercises between short pump sets.
