Sounds like a challenge to me, so let's give it a go, shall we?
Firstly, long esters would almost always refer to enanthate or cypionate , with half lives of 10 and 8 days respectively.
His statement that it takes 7 days for these long esters to kick in is also, erroneous - the truth is , it starts working the second you inject it but it will take 2-3 weeks to reach peak blood hormone levels.
Moving on......
It's interesting that he would mention such details as using benzyl alcohol in his homebrews but leave out mention of any benzyl- benzoate, this seems to indicate he was trying to stress the "sterility" of his oils (fairly obvious in context) and left off listing it, as you really don’t “have” to have bb in oils but it helps thin out the mixture and allows you to use less ba, making the shot painless. It's almost inconceivable that he wouldn't have at some point been counseled to add some bb to his brews, in light of the circles he moves in.
Can we skip the receptor nonsense? Only morons
still subscribe to the belief that androgen receptors down regulate (although not long ago we
all thought this) and of course the idea that different esters will attach to different receptors is also an outdated, debunked premise (let's remember that Ryan was also smoking most of the weed on the west coast during his heyday LOL).
His take on insulin is typical for the time he's referencing - all the top powerlifters were using GH and insulin by then , but few REALLY understood it's mechanisms in a way as to be able to describe it accurately, they just knew it worked.
Things are different now and even gym rats understand GH and insulin a million times better than just a decade ago. Obviously water retention although present, has nothing to do with it, although if we simply substitute "glycogen" for "water", his statement makes more sense LOL!
His statement:
"Basically what insulin does is it shuttle’s all what you consume in your body into your muscle." although simplistic, isn't exactly wrong per se. There's a lot more to it - insulin transports certain amino acids directly into the muscle cells. increases activity of glycogen synthase, inhibits catabolism of protein, increases fatty acid synthesis in the liver, and very importantly, it will not convert glucose to fat if it can first store it as muscle glycogen.
Ryan mentions mixing powders in tang for oral administration, while this would be feasible with winny, Dbol and several less likely steroids, we know from other statements that Ryan is alluding to testosterone which of course is woefully misguided at best.
I think I've pretty well covered everything, shouldn't be anything everyone didn't already know.

An interesting aside, although most laypersons consider Westside the cradle of modern powerlifting drug knowledge, it was actually Scott Mendelson who was responsible for pioneering GH/insulin use to it's current levels in powerlifting......
If you'll indulge me one more slight tangent.........

I was always more impressed with Ryan's girlfriend at the time, Kara. Out of all the roided out, elite powerlifting chicks , she wore it best.
