Since you would like some opinions, here is mine.
If you’re only doing 4 sets of legs per week, you’re essentially getting the same (maybe even less) volume than someone who trains legs hard once per week. If you do grow, just know that most of the work is being done by the soviet sports supplements. 4 sets of anything per week is not sufficient, with the exception of heavy deadlifts, and even then some people need more than that.
If you’re training 4x/week, I hope you are doing one day one, one day off for your split. If you’re training legs 4x/week with one set each time, you’ll be fine. The whole purpose of steroids is to enhance your recovery. By only doing one set each day, you aren’t doing enough volume to feel it the next day, especially since you’re on gear.
On the positive side, I think you’ll see some good gains on your upper body.
I don’t know what “chargings” or “strides” are, but I would replace them with a squat variation. As for the deadlifts, unless they’re clean deadlifts, I don’t think you’ll fatigue your legs even close to enough to stimulate growth.
My final opinion is: don’t do steroids. If you’re dead set on doing them, train more frequently and with higher intensity to get your money’s worth. Training with low volume 4x/week on steroids is like riding your bike everywhere when the sports car you’re leasing is sitting in the garage. If you’re going to spend the money on steroids, train like you’re on steroids. When you eventually stop taking steroids, then training 4x/week with lower volume seems like a better idea.
