the good old DHEA, but you better read up about it first as it can have some funny side effects with the odd person, you could also back it up with some Tirbulus, will do the same thing but without any side effects, they will both boost your testosterone, your libido and your energy levels, you can google Tribulus for any more info.
Your problem may not be related to T level, there is a general tendency among men to blame T level for all their health issues, where as all that they need to do is to concentrate on their diet and regular exercise. To me your T number looks really good.In spite of good diet and exercise, if you are still worried about hormones, look at your estrogen level, thyroid, adrenal and prolactin levels. If they are good, do a general health check up by a physician and find out if you have any other health issues. Often increasing the T level, where it is not necessary, may lead to more health problems than without it.
