Yes. I have done all that. Coffee, coffee plus l theanine, plus Mg supplement, plus vit supplements, lifting (at 155 lbs, I had dl 375, squat 265, front squat 225, bench 185, ohp 135, clean and jerk 135, snatch 115), 23 min 5k (untrained, I got my running from daily Barry’s class), rhr 39 bpm, HIIT every morning, sleep 10 pm to 6 pm. Many variants. All these are outclassed by even modafinil. And that is a candle to the sun that is amphetamine.

Only reason I don’t use the drugs is I want to avoid habit formation. Afterburners on, man. You don’t know the fire till you’ve seen it.

Now I am like a family man, but you can pour gasoline on youthful bonfire. Probabilistic failure possible but if you’re lucky, emerge unscathed.

I'd rather be unproductive than live that intensely, drugs or early bed time and intense exercise nonstop.

I do exercise because it's fun, rather than to work more.
