Clinical research still hasn’t determined a hard threshold level for when symptoms of low T begin appearing . Some recent research suggests that symptoms of low T might begin appearing in men when their total testosterone level dips below 320 ng/dl . According to anecdotal evidence from the owner of Peak Testosterone, many men start noticing low T symptoms when their total testosterone dips into the 400s . Of course, it’s anecdotal, so take it for what it’s worth, but it’s probably a good idea to stay above 500 ng/dl if you don’t want to experience symptoms of low T.
The thing is that fenugreek extracts haven’t always performed this well on scientific studies. Although in rodents, the extract increased muscle growth, it failed to have any impact on circulating testosterone levels 5 . In an effort to replicate the first human study sponsored by Indus Biotech, Bushey et al. found that in their trial, fenugreek did not increase either free or total testosterone levels, but it ended up lowering DHT due to 5-a reductase inhibitory effect 6 . Lastly, a study using 600mg/day of fenugreek extract called “Testofen” on healthy male subjects, failed to show any increases in testosterone levels 7 .
