The product I was looking into contains a 20% Phytoandrogen extract. Here is the description. Looks like a good product.
TONIC's main ingredient is a newly developed and isolated phyto-androgen which targets the androgen receptor causing it to fire as if testosterone itself were present therefore causing androgenic and male-creating changes. There is research that supports there is a phenomenal synergy between the phyto-androgen chemical found on this formula, testosterone receptors, and the testosterone hormone itself.
Du Zhong: Binds to AR and mimics testosterone, enhances effects and activity of already present testosterone hormone and also increases Nitric Oxide production ( lowers bad cholesterol, promotes healthy sugar regulation, anti oxidant, repairs tendons and ligaments, anti hypertensive and more )
Divanillyl 95% ( not 60% ) : frees up unbound testosterone which is good and will increase circulating testosterone ( synergy, see Du Zhong above )
L Carnitine L Tartrate : it increases the number of androgen receptors, more receptors means more androgen receptor stimulation and more synergy.
