Basically he wants to and I want to peak his conditioning to max, just so he can experience what it is to have such a dramatic lean physique while being strong as F and having sex like a champ

Literally I was intending the use not for a long term goal but simply to peak his conditioning over 3 weeks, like he will look good before on the mast test tren but adding in halo and another conditioning compound and maayybbee low dose SD or Anadrol to add fullness will just give him that "wow" factor.. that motivation when he is all unmotivated because he's puffy and bloated on a bulk he can look at the photos and his memories and think "I am going to look even MORE conditioned than that AND much bigger!" snd it gives him something to aim for again
