I wouldn't take M1T for your first cycle. Too harsh of a substance and too hard of a shutdown for your first time. That's where most of the perspective you mentioned comes from.
I think the S1+ idea for 4-6 weeks is a much better bet for you. You will still see great gains in strength and size since it's your first cycle. I wouldn't be shocked at all if you put on 15lbs assuming your diet is in check and you have proper PCT.
Speaking of PCT, I wouldn't use 6OXO alone. Use nolva, or even clomid. If you alread have 6OXO laying around, some people say they see better recovery with it and Nolva.
