That’s a classic bread and butter cycle right there, but honestly, at 160 pounds and 9% body fat, you are already shredded. You’re gonna blow up on that combo. 500mg of Test is a lot for a first or second run, so you might find 300mg is plenty since Dianabol is so damn powerful on its own.
Just a heads up, Dbol is notorious for making you hold water like a balloon and putting a beating on your liver, so definitely don't push the oral part past 4 or 6 weeks. For the Test, 12 weeks is usually better than 8 because it takes forever to actually kick in and start making magic happen. Just keep an eye on your blood pressure and have your estrogen blockers ready, because Dbol will turn you into an emotional waterbed if you aren't careful! Stay swole but stay safe.
