Just came across your post and pretty curious to hear more about your results. I don't take many supplements, but zinc has had a beneficial effect in that regard for me. Maybe check that out as well.

Also I use a Nutribullet juicer and the recommended recipe for boosting testosterone is a few slices of beats, olive oil and pumpkin seeds in addition to some other greens and fruits. I've not done it more than a few times so not sure about cumulative effects, but I did feel more aggressive from the single servings I've tried.
Hope that maybe useful to you.
