It seems what would be best is something topical that did not "go systemic," which blocked androgen receptors from receiving DHT. I have been tiptoeing around this topic because, while I desperately need testosterone supplementation (my levels have never been high and they're now in the toilet), my situation is made more complex by having a metabolic disorder wherein I must avoid the estrogens (and since testosterone is partially metabolized to estradiol, I would need an aromatase inhibitor) and one of the few attractive features I have is a head full of thick wavy/curly hair, nice enough that it had been requested I grow it out and donate it for wigs. I am hesitant to gamble with one of my scarce obvious assets. So, yes, I definitely want to find a counterbalance that would not kill the libido (I have almost always lacked) I would like to, uh, relaunch more successfully.
