The premature ejaculation could be from too low histamine levels.
Histamine receptor could be super sensitive, and then during sex , histamine gets released and boom reaction.
if NADPH is low, this would decrease tetrafolate and this will lower histidine.
As you said, you genetically make little DHT.
this means that probably you are genetically g6pd deficient. this means you make very little NADPH as it is.
May be this is why you crashed on finasteride.
If you genetically had low DHT, question is why you took Finasteride. Finasteride is to lower high DHT.
this is why many people with g6pd deficiency CRASH on finasteride WHILE ON IT and not off.
we have at least 20% on propeciahelp who crashed WHILE ON FINASTERIDE since finasterid kept binding their NADPH and they could not make more of it , since they were g6pd to start with.
And their hairloss situation is from lack of BH4, which is made by Tetrafolate))) and
and they never needed FINASTERIDE in the first place
The hairloss happens when you dont make nitric oxide. if you are g6pd deficient genetically you make very little NADPH.
and this decreases your tetrafolate and folinic acid. which basically tells your HAIR To grow. folinic acid makes DNA.
this is why folinic acid is used to restore hair after people use drugs that kill NADPH for cancer
And if someone is g6pd deficient , then this someone genetically will make very little DHT. and at the same time. that someone will have hairloss
since you make very little NADPH which has your folinic acid very LOW. and thus you have very low BH4 which is cofactor in eNOS.
