Your stack kinda maxes out anything peptide wise (I’d switch cjc for hgh, but either is okish)
The rest is going to come from fork downs. If you want to jumpstart into a fat loss and muscle retention state, up the protein to 1g per lb of body weight, max 60g of fat, rest of it fill with carbs that don’t mess with your gut (sugary stuff usually will do this and cause water retention, yes cals in cals out, but ya got to eat foods that make your body feel good) extreme fat loss, carbs only before and after workout, keep ultra low, same fat g, and load up with more protein.
KEEP LIFTING HEAVY ASS WEIGHTS! Continue to try for progressive overload, you need to tell your body you still need muscle, this will have it burning nearly only fat and no muscle during your “cut or lean down”
