I could voice my opinion on running Anavar solo but it might be a waste of time. Sooo....
Looks good man, it will work but not as much as you might think. Use the Nolva.. Your balls will thank you. Anavar isnt very harsh but it will still shut you down just like all exogeneous hormones. You might not have to run it as long but I say run it for 3 weeks 20/20/10 and you will be golden.
Look into test. It gives very clean gains. Look at my log. I am up 15lbs and down 3% BF in 12 weeks for my cycle. Test is 50% Androgenic and 50% anabolic making it a great "base" for a cycle or to run it solo. Most people who say you "blow up" or "gain water weight" are focking idiots who dont know how to control estrogen, train properly or use a proper diet. I can "blow up" naturally.. candy, steak and whoppers all day. I will gain muscle while doing that but also gain twice as much fat.
Diet is key and how you diet effects what type of gains you will see.
