This is an interesting question, that I would like to see some opinions on. If you were a bit heavier, and asked about a 20 mg dose for 6 weeks, I would say that you would probably gain more than 30 mg ed for 4 weeks, based on my experience. I do not think that 10 mg will do much for you though. So in my opinion, the answer to your question is yes, I do feel that Havoc at 10 mg ed for 6 weeks would yield less than 20 mg for four weeks, for you. This is just my opinion. I would try 10 mg first and see how that feels.
