if you have only 2-3 weeks of Prop I would close with it to shorten the amount of time you have between your last injection and your PCT
if you have a lot of it I would go:
Weeks 1-4, 13, 14 Test Prop 100mg eod
Weeks 1-12 Test Enan however much you are planning on running
~5 days after your last Prop injection... PCT
