It depends on the test dosage. Test for 12 weeks would be a hell of a lot better for your body than PP and SD for 6. Plus I think you could accrue more mass over 12 weeks than six. Those compounds are methylated and throw your cholesterol and liver values all to hell. You'd probably feel better with test as well.Dosage depends on your size and experience, but 500mgs of test cyp or enth a week is a good conservative dosage for test only.
If you want to incorporate one of those compounds, you could kick the cycle off and end it with a moderate dose of PP or SD. I've used superdrol for this and it worked well. Either that or test prop. You'll want to end it with these quick acting compounds because while the long ester test is decreasing in your body, you're totally shut down and you'll want something in you to keep you in an anabolic state until PCT starts. You can use orals or short ester injectables (injectables are healthier for you).
