Consider this - if you're running 200mg test and 25mg anadrol that's 375mg total weekly anabolic load. If you run 300mg test and 50mg anadrol that's 650mg total weekly anabolic load.
Anadrol can be very harsh on some people's bloodwork and digestion and is also for this reason not recommended to to be run for 12 weeks, 4-6 weeks tops is more appropriate.
If you ran testosterone at the same total weekly anabolic load as your test + anadrol, over the 12 weeks you would put on probably the same or slightly more actual muscle with better bloodwork, but less strength.
If you run the test + anadrol you will get stronger and look fuller but the actual muscle gains will be similar. Although your bloodwork will take a significant hit by comparison.
Alternatively if you are set on using anadrol you could look at running the cycle with test a bit higher, then throw in anadrol for the last 4 weeks at 25mg pre workout for 2 weeks then if tolerated can consider 50mg pre workout for last 2 weeks pre workout.
I personally prefer to get the most out of the least health impact, so if it were me I would go test a bit higher with no anadrol and have an ai on hand if needed. If I was going to throw an oral in for additional strength I prefer Anavar at 40mg pre workout for the last 4-6 weeks.
