Testosterone my man when I was 19 I was ripe with the shit. I ate and worked out constantly. I was up for 4 days 48 hours 30 minutes of sleep an then 47 hours. I would sit their watch anime for a few hours get on my bench press do 100 reps with 85 lbs ( its all I had.) Ocassionally shitting and eating and talking to my gf on the phone ( it was summer break) it was weird walking out and seeing my parents asleep. I'd shrug make a sammich pet my cats go back to my room to workout more. I miss being muscular...I should really start working out again.
