Smolov that is not adjusted for drug free should not be used drug free.
Way too advanced
Westside is not too advanced, you did something wrong. I got amazing gains when I was 14 off that.
That said, you may respond better to westside for skinny bastards. IMO it is better at your level. I think the bands/chains/ect are too much for your level.
A lot of people like 5/3/1... I am not a big advocate of it. Its okay, but just okay. It is better than no program or a self made program in most cases, which is why people see results.
Texas method has had some success with guys I know. They were about your level. Basically added a plate to every lift (roughly) in about 20 weeks.
That being said, my first year on westside, my max squat was 315 when I started, and was 425 like 11 months later. Same gear for both. Same bodyweight. I was like 14 when I started, 15 when I did that. Then I started overtraining massively and stopped making gains.
That was on the basic westside.
Then I switched to WS4SB and gained some mass and tons of strength.
Then back to something in between, and vary stuff as needed.
