Exactly, couldn't have said it better myself. Also by there being a slower absorption rate you can achieve higher levels (of test) with less test. Everyone of my friends that are on HRT, all have higher then needed estrogen because the doctor they go to has a one size fits all mentality (200mg cyp per week IM administration) and that is just doesn't work. I go to that same doctor and use 125 of test cyp for hrt (sub-Q) and always have levels slightly higher over than a 1000 (test) and estrogen under 40. I strongly advise the sub-q method when on HRT. Try it, it can't hurt. It very well could allow you to stop all use of AI's. Most AI's damage your lipid profile, but Exemestane seems to be more lipid friendly. When you get the chance read Gear Depot thread with Q and A with Dr. G. Be good.
