It's called "Muscle University" and follows Woody (real name Sebastian Wood); a handsome, sassy, self assured (some might say cocky) bodybuilder with a cheeky Instagram persona. Woody attends Montgomery University of Bodybuilding & Fitness, the only school in the world dedicated to turning it's students into pro bodybuilders, where lessons include Posing Practice 101 (only posing trunks required!), Anatomy & Aesthetics and A History of Bodybuilding.
I'm sharing the story over on the Muscle Growth forums here (it's a bit too much to post in multiple places). It has a different feel to "AJ & Noah" but there are some similarities. There's quite a few references/Easter eggs to that story too.
My friend Reeddune is also working on some illustrations for it. And on that subject, I've been sent not one, but two AMAZING "AJ & Noah" illustrations (or "fan art" as they've described them) which you can see below! The first is by a guy called Alexendre86 (more on his Tumblr, Twitter, Instagram and DeviantArt pages) and the second is by a guy who goes by the name of Brawnygods who so far has a Tumblr and Instagram.
