I would suggest he go with the sust and run that on its own at 500mg per week for 12 weeks. That would be a great first cycle. I would definitely not run tren on a first, second, or even third cycle. I would set it up like this:
Weeks 1-12
Sust 500mg (inject 250mg twice per week)
Aromasin 12.5mg EOD (ag-guys.com)
