Please tell me how you would run a Test 400 and a Tren A Stack?

Would you run them both together at the beginning and then tail off at the end with the Tren and keep the Test up?
EXP. Test 1-12 w Tren 1-8?

Or would you run the test only to start and then bring the Tren in afterwards?
EXP Test 1-12 w Tren 5-12?

Also, what would your Post Cycle Therapy look like?

Clomid Treatment for four weeks starting two weeks after the last injection?

Please help i have some questions to figure out
