@solokwa Whilst I’m always wary of trusting random people off of Instagram, pretty much all of that advice is sound and applicable to both natural and enhanced lifters. If anything I’d argue it’s more important for natural lifters since you simply aren’t going to recover as well or benefit from insanely high amounts of volume as an enhanced lifter. Not to say enhanced lifters don’t need to be dialled in, but you can probably go a long way with doing stuff wrong when you’re on gear as opposed to doing everything wrong when you’re natural and seeing next to no progress before long.
The sentiments in the post you linked are echoed by a lot of knowledgable people within that field. I’d recommend checking out Sean Nalewanyj (underrated GOAT), TNF (intensity through the roof), JPG, Ryan Jewers (if a bit too sciency for my liking), Jeff Nippard (also has some wild recommendations but another legend), Dr Mike from Renaissance Periodization (utterly unhinged and tends to lean towards more volume with slightly scaled back intensity but amazing advice nonetheless) and Max Euceda (lad is young but knows his stuff). Hopefully these guys, and I’m sure many more, will help shape a really effective way of training for you.
