its a poorly done study IMO, and funded by manufacturer. plus is lowering DHT necessarily a good thing for muscle growth? Of course total T goes up if you lower DHT + Estradiol, but does that help build muscle?
for an example of what I mean poorly done
37 years to 67 years with an average of 55.6 years and body weight ranged from 68.4 kg to 102.5 kg with an average of 80.3 kg. The ages of the 2000 mg/day dose group ranged from 53 years to 70 years with an average of 61 years and body weight ranged from 67.9 kg to 95.3 kg with an average of 84.8 kg.
so both average age and average weight is significantly different between the two groups. And of course, no placebo group at all.
There were no food or exercise requirements or restrictions.
so they also could have started exercising
more, which could also change those levels.
