So to really understand what works best you have to understand synergy (or how 2 or more compounds work together) for the best possible results on the body for aesthetics, strength and overall health.
Some side effects from dht can be anxiety, aggression, irritability, hair loss etc. This can certainly be greatly exaggerated once you start running multiple dht compounds. For me personally I would feel like crap on those alone.
So also you have to understand that if you run a epiandro Winstrol cycle you would have an extremely dry cycle. Again considering how the body works you would see an increase in strength while the joints tendons and ligaments won't be able to handle the extra stress as well as if you were running something wet with it. The extra water weight in the joints etc will actually absorb a lot of the stress and help your body and you will feel much better. Estrogen is actually a great hormone you just don't want too much. You have a wet compound and a dry compound working together synergistically giving the body everything you need to make the most of it and feel the best. You will just feel better in my opinion as test, trest and 4ad are all known for giving a feel good sense overall as well as mentally. Again its the synergy of a wet and dry steroid working together that makes it better. And the synergy between 2 dht compounds solo that would make it worse in my opinion.
You have a compound like anavar which I absolutely love. I have run both anavar and Winstrol and really like them both however I choose anavar all day over Winstrol today. Reason being is Winstrol is really hard on the joints and harsh on lipids. Anavar actually has collagen synthesis properties so it actually makes your joints etc feel better. I just feel better on anavar although I think Winstrol is a better builder. Both drugs are good for strength. Anavar gives great pumps and muscle fullness within a couple days. Its great at building slow lean mass that you will most likely keep and will be quality gains. Winstrol is great for building and works pretty fast as well. I would run either of these a minimum of 5 weeks. If you absolutely must do 4 weeks I would choose Winstrol because I think its a little faster acting than anavar in terms of gains after 4 weeks. I would definitely run an extra week and go 5. I think you would make more gains in that last week. Anavar for 6 weeks with a good base like trest, test or 4ad. Transdermals (test or trest) make the best base. I actually use td test for trt. I love it and only really use small amounts of one or two compounds when I want to run anything. For me adding 40-60 mg of anavar for 6 weeks produces great results for me. I can gain about 6-9 lbs and lose about 1-2% bf. Running Winstrol at 50/day would produce similar results with slightly different effects in terms of aesthetics and how I would look.
