So everyone has an opinion...so here goes. If you want to gain "lean" and look "lean" stay away from sustanon.
Back in the day sustanon was a part of nearly every bulking stack I did and I loved it, but for me, excess water weight was common and accepted as a part of bulking. Sust does wonders for bulking, but "Sust and lean" do not go together if you ask me.
Recently, I started a sustanon stack for the first time in 15+ years and was amazed at the water retention. Immediately, I was reminded of the age-old talk of the "sustanon moon face". But everyone's reaction is different...maybe you won't gain as much subcutaneous fluid as I do.
Plus equipoise...to me... is for clean gains, usually in a cutting stack.
If you want lean muscle....try a single ester testosterone plus EQ. If you want to bulk, do Sust and Deca or another core bulking compound. Just my $.02
