Matt,
For Christ's sake, think less about the AAS and more about Buspar or something else to calm your nerves. I pretty much hated Sarcasm/Mirza, too. He was a royal asshole with a sophomoric sense of humor and his ugly fat ass never backed up a single claim. Small wonder he was practically butt pirate mates with Abeles the borderline pedophile (ask the mods; I wasn't privy the the nail in the coffin, but that creepy arrogant fuck spent *years* talking about sixteen or younger).
That said, to quote Quakerdolts, you're melting down here, and we're talking full containment breach! You're arguing with people now about your hair, teeth and good looks?!
Take a break from here for awhile, my man. Keep upping the calories incremental like and forget about chasing strength PRs just so you can say "I did seated presses with the 110s." The strength will come easily, even with stricter form. Set a new baseline with much higher, stricter reps, upwards of 20, and add a bit of weight every session until you're down to 6-8.
P.S. -- As-is, I cringed watching your machine fly video. Pure ego training. Your chest was collapsing and your shoulders came forward from the very first rep, dude! Cut that 200 to 100, get a full stretch on every rep and hold it for a count of five at the bottom, without the weight touching the stack. FEEL that shit stretching your pecs.
Then, initiate each rep with controlled power, keeping your chest high as can be, and pause in the fully contracted position for a two second count, squeezing the life out of your pecs. Rinse and repeat until utter failure, including partials. NO leaning forward to complete a rep.
I doubt you'd need a second set of the same, nor do I think it'd be productive -- not after the other movements you'd probably do before this

. Flat bench, incline, and maybe some machine press, likely Hammer? (I can imagine you loading up that Hammer Iso-Incline heavier than you should. Don't lie now

.)
If you give this your all, you'll do well, mate. Just stick to a plan, stop obsessing over numbers, and as I said, if it takes a break from Getbig to put that Autistic brain on track, do that. You're too easily distracted and defensive from the input you get here, even though most of it is constructive. Train, enjoy the gains and come back when you're more secure in what you're doing.
