Dhea and other neurosteroids play a very significant role in the human body especially when it comes to adrenal function which a large percentage of us here have issues with.
The problem with that is the bioavailability. Sublingual or transdermal is the way to go.

Nevertheless, a growing body of evidence supports the notion that DHEA is not just an overrated dietary supplement but a useful drug for some, but not all, human diseases. Large-scale randomised controlled trials are needed to fine-tune the indications and optimal dosing protocols before DHEA enters routine clinical practice.
Dhea is also highly recommended and hormone replacement therapy

Pulmonary artery (PA) hypertension was studied in a chronic hypoxic-pulmonary hypertension model (7-21 days) in the rat. Increase in PA pressure (measured by catheterism), cardiac right ventricle hypertrophy (determined by echocardiography), and PA remodeling (evaluated by histology) were almost entirely prevented after oral dehydroepiandrosterone (DHEA) administration (30 mg/kg every alternate day).

The authors conclude that treatment with an activator of calcium-gated potassium channels, dehydroepiandrosterone sulphate, known to be well tolerated by humans, reduces hypoxic pulmonary hypertension
