This month's issue mentions fenugreek as a useful supplement for balancing hormones - in particular to boost testosterone.
As someone who's just starting to run over an hour in marathon training, I'm interested. This is mostly because want to retain as much of my cross-training muscle as I can (not that there's much, I just want to keep my cycling legs).
Does anyone have any opinions or experiences to share about fenugreek?
Ironically, the main google search results talk you to Livestrong pages. They're no stranger to testosterone
