that doesnt mean much though.
mine are 18 and bit more dead cold(pumped shouldnt even count), but lean.
every muscle appears bigger when lean, so measurements are kinda meaningless.
i could have 20 inch guns within 2 weeks, if i simply ate 15k cals a day.but theyd be flabby.
Mine are not flabby. Not superlean. I have abs and veins.
In the grand scheme of things it does not mean anything at all. Just a milestone I hit without actively and directly pursuing and was a pleasant surprise.
It was measured using one of those wee tape measures like this.
