im a firm believer in not going overboard but also getting the most out of something when you do it... you would not want to exceed 500 mg per week, but me, that's where i would start... you will have people say they got great results and 250 and some who say they didn't get shit... that's the beauty of this, we all react differently... you may want to start at about 375 the first week or two to see how you react, but me, im saying 500 man... the problem with this question is your going to get a thread full of people who did it one way and people who did it the other and ultimately the decision is yours and what you feel comforable with... since its your first cycle, it may be wise to to test the waters a bit the first 2 weeks and do the 375 and go from there... i would always rather be moving up than having to lower dosing...
also, whats your pct look like and i would have an AI on hand as well... arimidex would be fine...
