Just an FYI, one of the guys here said that anastrozole was killing him with side effects, but Aromasin treated him great.HCG is a LH mimic, so it can trigger your body to make its own natural testosterone. You may need to further adjust your injection dosage while on HCG. As mentioned in a previous post, HCG can also trigger elevated E2 (it does for me at 400 IU 2x per week). I only need a tiny dose of anastrazole to address elevated E2. I adjust by dissolving four 1mg anastrazole tablets into 16 mL of quality vodka (a dropper bottle). To dose, I shake the mixture then measure out 1/2 CC of the solution in a tuberculin syringe (slip-tip needle removed). Voila! 1/8 mg of anastrazole right there - then down the hatch it goes same day as my T shot. This is far more accurate than splitting those tiny tablets into slivers. This keeps my E2 level between 20 and 30 consistently. The "boys" are at their full size too (they were the size of marbles and didn't "hang" normally at all prior to starting HCG).
