Natural training is shit unless you get lean before you start training/before you have any mass to lose. Simple formula for beginners/natties should be: get lean, eat well and train consistently, build a base and then if you want to take it further, jump on the hormonas. The problem with the internet is you get caught up in too many scambags lies and bs.
From 17-19 I followed the layne norton/scivation shit first. Then the serge nubret principles from his bb.com thread. 2 hour workouts 6 days a week, no steroids, eat 0 carbs except a couple of leaves of lettuce to get ripped etc. Turned into a twink. At 17 pre-trained I weighed like 140 but after this I got down to maybe my lowest of 120 llbs. I would never diss the great man though, I think he was just trying to keep the kiddos healthy. May he RIP.
My next phase was muscular development and the jumbo palumbo keto diet. This kept me at twink status.
After that I found the holy grail: Danta and sons lol. To give him credit, from the age of 21-23 DC and perma bulking took me from like 135llbs to 200 llbs at 20-23% bf (5-6). The only thing they don't tell you is that as a natural, you won't be able to diet the fat off without going flat and going back to twink status. This leads to many failed 'cuts' when you get disheartened by losing size in clothes.
I've found getbig in the last year but I wish I found it earlier.
