23-24 can do well with testosterona only ,, your gh is good still in the tip ,, 23 is probably best age for bodybuild growth,,not maturity but growth!
npp is godo drug but you need it to be legit,, tesosterona with optiman natural gh = good physiqe that hard to compete against especialy at this age,, only thing that can take you to next level is trenbolona ace and syntetic gh
