would that be possible to get 20" arm without drugs?

All depends if they are lean.  A truly lean 18" arm is a rare thing for a guy not using drugs.  How many fat grandmas have 20" arms? I will answer; far too many.  Again a guy with an 18" smooth arm on a lifter looks impressive but it's no where near a ripped 18" arm. Mentzer said with no pump weighing about 210 ripped and his arm was 18 5/8".  All these guys showing pictures of their 18" arm don't look anything remotely like Mentzer's arm.  An arm measurement is also a matter of bodyweight and structure. A guy that weighs 240-250 will easily have a 20" arm if they train but that's not saying it will be impressive.

The answer: Probably (IF you have elite genetics). But modern natural supplementation is a must.

Creatine monohydrate, Nitric Oxide, BCAA's, Test Booster, Ecdysterone

High protein diet, obviously

Pyramid sets, lots of compound chest and back

Concentration Curls (Arnold Style) for the peak

I took my arms to 19". Probably could take them to 20" but I don't care to blur my six pack, obliques, serrati

None of that is right.
