how anticatobolic is 500-750mg per week of test e?
 

I know this is a hard question to answer and there are a lot of variables but I would really like a little insight here.
If there's one thing I've always been good at its shredding fat. I track every calorie and macrothat goes into my mouth. Normally I will dial in my calories to where I'm losing .5-1pound a week.
I'm planning on cutting for the final 6-8 weeks of this cycle. I'm running 500mg test e per week. My goal is to get as lean as possible before I do my pct.
Basically what I'm asking is. Can get away with going on a extreme cut for 6-8 weeks without losing muscle while on test?
Also considering jumping to 750mg per week for the good. Good idea or not?

The simple answer to this is Primobolan at 600 to 1000mg per week.
Primo is the only steroid that can build muscle while in a calorific deficit

i know guys whoi have done it with test and tren dropped about 10pounds of fat but stayed around the same weight

Plenty. I ran 200 mg of test cyp for 12 weeks on an extremely calorie deficient diet and didn't experience any muscle loss, even with 2-3 cardio sessions a day.
