I doubt you will lose muscle with a proper deficit with good nutrition, rest etc. So no need for this cycle to do this. I will say however that the cycle you proposed is acceptable if you want to do something.
I respectfully disagree with the the idea that taking so litte is not worth it while taking more is better. Will it generate huge results? Probably not, but "TRT+" is what you're talking about doing. Many do that sort of thing and like the results. 125-150mg of test e + 20-40mg of anavar is pretty typical for a "boost" even on this forum.
Another route is enclomiphene and or/HCG + an oral to get your feet wet and/ or satisfy your curiosity. It's low commitment and it's easy to recover from as enclomiphene or clomid prevents shutdown on something like this. You satisfy keeping your natural test level (or even boosting it) while using the oral. No need to potentially spending months recovering from a cycle with injectables just to get the experience.
Even the oral on it's own is typically not hard to recover from as it's in and out quickly. OTC test boosters work well for a PCT from this as well.
