First off......Welcome to Steroidology !!
Now as far as that cycle goes, it's pretty light for a fourth, and with Primo, chances of you getting any legit stuff is kinda rare, so this is what I would suggest.
Test Enanthate or Cypionate @ 500 mg/week for 10 weeks
Deca @ 300 mg/week for 9 weeks
Clomid therapy, two weeks after your last Test shot.
