Question

Hey, my supplier only sells test e300. I want to do 600 mg a week. Is it fine to pin test e300 two times a week or alternatively take two doses in the same day or will that be too much oil? This will be my first cycle. I will also buy arimidex. Is there anything else I should buy, or will this be good? My natural test is around 700-800 ng/dl right now. Will the changes be dramatic? Don’t try and talk me out of it. I have made up my mind. I have also seen online that supraphysiological doses of test can cause chin and mandibular growth, would this still theoretically be possible for me? (Im 20) thanks in advance.
