Some guys in another group I am a part of have been experimenting with this, as well as applying high concentration Topical DHT to their members and have seen some results. DHT is tough one though because it will shut you down so if you dont plan on doing a PCT dont even think about it
The thing with DHT, is a hit or miss. And why is that. Because there is not enough science and research study behind DHT and potential penis growth. One reason why there is not enough research is because it falls in the field of epigenetics which is rather new.
This is what happens with DHT:
- If a woman start using it along with testosterone, she will see a huge increase in size of her clitoris.
- If a man with diagnosed micropenis is put on therapy with DHT and testosterone, he will see a big increase in penis size
- If a teenager born with primary hypogonadism is put on a therapy with DHT and testosterone, he will see big increase in testicular size and penile size.
- If a group of healthy normal adult men start a therapy of DHT and testosterone, they will randomly see little or "some" results to none.
The differences you see there is due to something called gene expression. On a healthy adult man, who was born from a healthy mother, his penis would have developed to its maximum genetic potential. Therefore no matter what kind of exogenous hormones you apply and at what doses, that penis wont change in size.
On the other hand, wether is a woman or a man born with some deficiency, that gene is still there coded to grow a certain amount of penis but never made it for multiple reasons. Gender, mother depleted of essential nutrients while pregnant, mother exposed to harmful environments while pregnant, etc. That gene, still has the potential to develop once the right conditions are created. In this case, the hormonal environment.
And you have lastly the third group in between where the male is considered healthy and fully developed, but still with some potential gene expression to develop. Those are the ones who see "some" results.
If you are not familiar with the use of hormones and how your HPTA (Hypothalamic testicular axis) works, I would recommend to stay away from it. Otherwise you can give it a try. True, it will shut down your HPTA but is only temporary and a healthy diet with high quality supplements of essential nutrients will restore the HPTA quickly.
