first time steroid user, cutting cycle..

Stats... 41 y/o 6'1 280 bf under 20%. Diet..6oz x4meals of chicken or fish or Turkey. Veggies and fruit intake about 2 cups a day. Carbs under 80g. Looking to do a cutting cycle wondering what would be the best one? Dose and how long?

You're going to hear so many ideas for this. I would suggest Test E for 12 weeks at 400mgs a week. It's a low dose for cutting and keeping it simple. Make sure you have all AI'a/Serms in case sides pop up... And a full PCT.

Diet is key here!

What's a more precise body fat?

Looking at your stats, I HIGHLY suggest you drop down to 14-15% before starting cycling, you WILL get worse side effects the more body fat you have (estrogen conversion and bodyfat are very related.) You should be able to cut to 15% naturally.

First cut cycle suggestion - get down to 15% naturally first if you want the best results and the least side effects. Suggested cycle: Test E 500mg/wk (250 mg 2x per week) for 12 weeks. Have AI's on hand, and your PCT ready before you start.

Just backing the other 2 guy here, diet is key and sounds like your heading in the right direction by knowing what you really are taking in. 500 Mgs of test is plenty to help maintain muscle while on a calorie deficient diet, but having a higher bf% can lead you down a road of potential bad sides hence why people suggest lower % when using AAS.

Really follow the advice in this thread these guys know what they are doing.
