SERM: A must
HCG: DO NOT USE IN PCT!!! Only on cycle.
Test boosters: Not essential but they are good to have
AI: Not essential but you can use them
cortisol control: Not essential but you can use them
40mg nolva is excessive. It's not gonna really have any negative effects on you but not reason to run more than you need.
I would run this is you are trying to be economical:
20/20/10/10 (add 2 weeks of 10mg if you are running a longer injectable cycle)
DAA (cheap test booster)
You can add in a cortisol control supp like Reduce XT or AI like erase if you want as well.
