Haven't used the cytodyne product, but then again I haven't used any product (save for creatine and fish oil) that hasn't been from Biotest in almost 3 years.
The methoxy product you should look into is Methoxy-7 that Biotest makes. Though I haven't used the most recent formulation, I have read various posts that have users falling in love with it. Use the search feature and you are bound to find a ton of testimonials. Good luck.
