Hi Birth, At 46 there are to things that can incress your testosterone, DHEA is one,and its a hormone, but please read up about it first as it can have the odd funy side effect with the odd person, ok and two is Tribulus, and its a herb, now both of these run along the same lines by boosting your testosterone, lifting your libido and kicking up your energy levels, now I take both because I had ED and now in recovery.
So DHEA start on a low dose say 25mg and take fisrt thing in the morning, reason your own bodys DHEA is at its highest then so it will help boost it.
Tribulus needs 8 weeks to get to full power, so after that only take 5 days out of 7 for both, reason its so your body does not get used to them and they work better.
And if you can get Tribulus in a herbal form, you can have it in Green Tea, I have a day on this each week, I take it with root ginger honey and lemon, I keep my Ginger in the freezer, I fine grate to the size of a egg, and zap it with the lemon in a micro wave 30 sec, the and the tea, I steep my Tribulus and Green Tea over night in a 2 pint tea pot, and after the first 2 mugs refill with hot water.
Is this what your looking for?
Good Luck
Hi and welcome, i have head that they can increase it but at your age you should have a PSA test done before, as if you are at risk for prostate cancer, adding more testosterone, it can increase the risk.
