So, I’m 17. I started training with weights in Dec 2013 with absolutely no knowlege/experiece. I got my squat from 80 to now 145lbs. I can deadlift 160lbs easily. Bench press on and off since my bench is broke. So would you say my beginner gains are gone and I need to use creatine? I am going to buy some whey soon. I am also trying to gain weight. I’m 147 right now. Trying to be 155 by mid-June. Any suggestions to add on to this. I did 5×5 training for almost 10 weeks a few months ago (got me to that heavy squat lol 😉 )
My question is my biceps are great and my triceps are”meh”. I’ve normally been doing 9 sets for biceps and 9 for triceps. Is this too much volume? I never feel over trained because I can’t do deadlifts or squats. Am i shooting myself in the foot for doing too much volume to force tricep growth? I do close grip bench press, skull crushers, seated dip machine, & tricep pushdowns. All of them burn! Mind muscle control is perfect. I am starting a lean bulk. It’s been about 6 months from last bulk so that might be why my triceps are still weak looking. Thoughts!? Thanks beast!
Furthermore, extracellular arginine does appear to be a determinate of nitric oxide release  (the CAT1 transporter that shuttles arginine is highly associated with eNOS  and inhibiting extracellular influx prevents eNOS activation  ) while intracellular arginine concentration does not appear to be associated.  Due to the transport being required but intracellular arginine not being per se required, it is thought that the colocalization of CAT1 with eNOS   may also play a role in stimulation of eNOS activity.
