Getting older? Take anti-oestrogens with your testosterone
In the study, 35 men aged between 22 and 73 with a raised LH level and low testosterone were given Fortigel testosterone gel for two weeks consecutively. Every morning they rubbed 3 g gel, which contained 2 percent testosterone, on their legs. The table below shows that after two weeks the older men had less total free testosterone in their systems than the younger men. That's logical: the older men get, the more SHBG binding protein they make. SHBG neutralises testosterone.
Nevertheless the older men's natural production of testosterone suffered more when they used the testosterone gel than that of the younger men. Below you can see the effect of the gel on the LH level, according to age. LH is a hormone from the pituitary that tells the testes to produce testosterone.
The researchers also measured the concentration of estradiol in their subjects' blood. When they measured the correlation between the amount of estradiol and the LH level they made a very interesting discovery: the concentration of testosterone didn't correlate negatively with the LH level – but the concentration of estradiol did.
It’s pretty clear what that means: give anti-oestrogens to older men who are taking testosterone supplements as well and the problem is solved.
Testosterone gels are not used much in the chemical power sports world. Nevertheless, the findings are also interesting for chemical athletes who use stronger stuff than gels. The study makes it clear that anti-oestrogens are useful to chemical athletes as they get older.
