LOL... I think I may have too. I can remember when I used to run 750 test all the time, no matter what else was in there. Then once for 6 weeks I ran 1500 test and 1000 tren E, and I believe anadrol was in there somewhere, because its my favorite vitamin.
Increased gains over smaller doses, ehh, sort of negligible but the side effects - YES, definitely a big upgrade there. But I can say I did it, in part after reading those "articles" about how "magic happens" once you get to xxx dosages and I can look back and say its pretty much bullshit.
Work your AZZZZZZ off, and even a modest-fair cycle of gear is a big kick in the pants. Side note, tons of stuff is out there to put bro science to bed and how you shouldn't workout past 45 minutes blah blah, thats fine. Everyone is different! As a non-gifted (other than I'm pretty healthy) white guy, bro science works better for me than anything else. I've trained with high volume, 2 hour 15 minute shoulder workout guys and I always get my best results there. My back workouts were always 25-30 sets and I had ok size and strenght, but after one 2 hour session (see avatar, I couldn't really close my hands) I always saw results right away. Kick your ass, try it at least for a couple weeks. If the rest and nutrition are there, just watch.
Regardless though I wish you luck, I really doubt you will die, but you will earn some experience! And there is nothing really wrong with that. Enjoy the shit out of it! And earn some wisdom in the process.
