Well, in such case a cycle of SARMs would be better suited for you. It does not require injections, and is much safer than steroids. SARMs do not have side effects, so they require considerably less ancillaries and a milder PCT. Therefore, my recommendation would be to run a SARMs triple stack - Cardarine GW-501516 at 12.5 mgs per day, Ostarine MK-2866 at 25 mg per day, and Andarine S4 at 50 mgs per day. Use them all for 12 weeks, and split the dosages in two - one taken in AM, and the other one prior to working out or PM. They are much more convenient than steroids are, as you just drop the liquids in your mouth. A little recommendation regarding S4 - for the first two weeks use just 25 mgs per day, so the two split dosages would be 12.5 mgs. Then, from the third week on use the full 50 mgs dosage, which will be split in two 25 mgs dosages during the day.
As for the aromatase inhibitor - it will do the contrary to what you think. Aromasin will increase free test levels, as well as it will increase IGF-1 levels by up to 25%. Also, by preventing estrogen buildup, aromasin will prevent water retention and fat accumulation. All in all, it is a very beneficial ancillary drug to use.
