I don't have a problem with medhis program for beginners. IMHO, the big compound lifts should absolutely be the core of any STRENGTH program. That said, this particular program is only appropriate for beginners or maybe maintenance.
If you want to make some progress, especially in strength, give 531 a hard look. If you like the Big 4, squat, bench, deadlift, overhead press, you will enjoy 531.
Personally, I would not be thinking about cycling until after at least 2 years of straight of solid, consistent, and disciplined training, nutrition and rest. You can get a LOT done natty if you dial those factors in. At your age, in a few years you will likely be thinking about trt... At that point, you will have a solid base and can blast and cruise.
And this concludes my way overpriced 2 cents on the topic.
