I've personally found that keeping it simple works best for me. I always start with an effective Starting Strength program or some variation of it with heavy, compound barbell lifts. After a while of making significant gains I outsmart myself and switch to a more advanced program like Westside or a split variation. After a few weeks, I over do it, start skipping workouts, start getting those pains in shoulders/knees/forearms and have to take time off, losing most of what I gained.
In my opinion, the best program/method is the one that you can physically and mentally sustain for long enough to make gradual long term gains without burning yourself out. For me that tends to be a three day Starting Strength modification.
I've been on Testosterone Replacement Therapy for the past year which has been a life changer for me. I highly recommend that anyone who suspects they have low-t levels, get themselves tested.
As far as pre-workout goes, I think what no one has mentioned yet is that there is a HUGE discrepancy between the junk products out there, and the products that actually have effective ingredients. Most products fall into the junk category. I've never been a huge fan of pre-workouts, because I honestly have always felt that putting that $40-$50 a month into high quality food gives me a better return. but again, that's just personal preference and if money is nt an issue for you, there are a few good pre-workouts out there.
