AndroGel......a testosterone replacement/supplement

Enlarged and sensitive nipples are a initial symptom of Progesterone induced Gynecomastia, what steroid users fondly refer to as bitch tits.

Progesterone can be aggravated by elevated Estrogen levels, which itself can cause another form of Gynecomastia and prostate hypertrophy. Elevated Testosterone levels from TRT (Testosterone replacement therapy)will automatically elevate Estrogen unless drugs called Aromatase inhibitors are used concurrently to prevent Testosterone to Estrogen conversion.

Aromatase inhibitors are an alternative way to boost testosterone levels versus TRT, much better I believe in producing less chance of these side effects, both require either the services of a skilled Endocrinologist or knowledge of these compounds, and/or the hormone DHT as the best anti-estrogen libido enhancing substance. The trick is to reduce Estrogen to that of a young man, but not too low, as this has long term negative effects on cardio, brain and bones. DHT is very effective for these Estrogen side effects and general male virility but if one is prone to male pattern baldness, beware.

This is a complex subject, can only post the basics here. The best place, that I know of, to get real deal info from both doctors and skillful laymen is the anti-aging and over 35 subforums of anabolicminds.com

I use the over the counter test boosting aromatase inhibitors from http://www.nutraplanet.com/category/anti-estrogens/ , the very best price and service place on the net to buy supplements, but I know what I'm doing with these.

On the less serious side, those products at Nutraplanet, my choice is ALRI's Restore as it covers mutiple areas, are great as a pre game warmup for a trip to places like Vegas, etc. 😈 These and a Prolactin reducer like Dostinex/Cabergoline will make a 40+ man feel and perform like a twentysomething again.

I'm a pro athlete, I have to know about better living through chemistry, ask whatever, if you wish.
