I want to do a lean stack and have never used m4ohn or 1,4 andro. However, I have read that this would be a good lean stack that is easy to keep gains. I understand that 1,4 andro is a prohormone that needs to be taken for longer to see results. Also is there a difference between the 1,4 andro diol and dione version? Is one better than the other? I was planning to take m4ohn 16-20mg ed and 1,4 andro 600-800mg ed for 6-8 weeks depending on how the side effects are and how the results appear.
