DHT only helps during puberty to have a large penis. As an adult, it contributes to enlarged prostate and male hair pattern lost.
Yes i'm 99% sure this, i've used dht alot all the derivatives also.
But not used dht gel right on cock...
Seems your right , 99% right you are.
But scientifically there could be one trick, that i'm not sure to try (would take too much time, i still have life)...Is to curb first the dht receptor sensitivity locally, like dht blocker creams on cock...
then stop and start dht gel...Doing this cycles back to back for months maybe years,
could result in bigger cock years later, but is a just theory...
Curbing the dht receptors , could stop erections also ,
this means have to keep erections still with something.
...Erections are neccessary to keep dick not shrinking, long term.
But end of all the end,
just using DHT gel could work if one has low dht/micropenis/puberty properly not finished. Other than that, everything else would be hard experimental stuff.
OR MAYBE if someone could very locally increase/use VERY ULTRA HIGH dose DHT, prevent that going systemic, could boost some growth there.. But this also would be science fiction.
Now i think , big problem would be that the dht will go systemic , gel even...And the body will get rid of it, block the receptors take in if neccessary...
So even using huge dose of dht gel seems somehow not possible...
Can't restict the penis blood flow too long before something happens.
Impossible mission.
And even end of this, even if this would work, girth would be the first that would go up mostly. length i doubt.
