It's not very clear what you're trying to say here. If you gained 4 pounds of muscle in a month, you've definitely not hit a plateau.
It's much better to train without supplements for as long as possible to figure out how your body responds to training/nutrition. The only thing I'd suggest is Grow!, Surge, and maybe some Spike for days you want an extra boost in energy.
If you want to reach your goals, you can't rely on some miracle pill to get you there because it doesn't exist. Only time, desire, and effort will get you there.
BTW, you'll get much better responses when posting here if you take the time to edit your posts so that we know you're serious about your question.
