by sexually bonded do you mean testosterone bound by sex hormone binding globulin? If so this is still incorrect. Test boosters increase libido in some but that increase isn't due to a noticeable increase in testosterone but in some cases is due to a very slight increase in free unbound T. Not nearly enough, mind you, to increase muscular performance but enough to make you slightly more horny. Most have ingredients like fenugreek, maca, nettle root, l dopa etc. Yes you feel something but it doesn't make you bigger or stronger. Mainly just broker.
