I have been taking androgel for 3+years for hypogonadism. I have taken doses ranging from 5 grams to 10 grams/day; my libido is through the roof regardless of dose. My total tesosterone has been all over the place but libido stays high. I will be 60 shortly and suffered from ED for he first time ever this past year although Levitra works great for me although I have no trouble masterbating to orgasm. I might add my spouse is very sexy and very underrstanding so I can't figure out why masterbation is so easy but I can't keep a good erection without Levitra?? I have done shots and my libido was great but NOT AS GOOD AS my libido on androgel. Any others have this experience? I would gladly settle for less libido and a harder erection but I don't think I can make that deal. Could it be that transdermals release a slow steady strem of testosterone which keeps my libido high? Any ideas? If you are healthy and have a low libido I strongly suggest a small dose of androgel (no I don't have money invested in this product nor do I sell it).
