People need to be aware that DHEA affects hormones, and that can have risks. I tried DHEA twice for about two weeks each time, and ended up having SVT (supraventricular tachycardia) both times. These episodes required ER visits.
Apparently, DHEA can have an effect on testosterone levels in some men, and therefore acts similarly to a steroid. While I'm sure the dangers are not as pronounced as actual steroid use, any kind of interference with hormones can be risky.
Use caution with DHEA.
