Im going to assume OP went with option A and is now a new IFBB Pro at 18 years old.
Jokes aside, you don't need much on a first run (assuming your of the age and development level to handle it). I am on the flip side though a would say 300mg of Test C paired with 300mg of Primo and you will see some pretty amazing changes if your training and diet are on point. You also wont need an AI at 300mg test unless you are very unlucky (so have one on hand)
Pre, mid and post bloodwork if you can so you can properly manage your continued use of gear in the future without destroying your health.
