From the information I found on this stuff, I don't think there is a lot to be worried about in the short term.
Some of the side effects may be a problem, But there is no information that I can find detailing the background of those experiencing these.
For example, there is one reported case of a man, taking this stuff who suffered heart arrhythmia. This might be a cause for concern until you look more carefully. Heart Arrhythmias happen to many people. I'm pretty certain that a significant proportion of people with Heart Arrhythmias have walked under ladders. And the report in the case of DHEA is one person. Frankly this sounds a bit like scaremongering, or another case of medical liars.
The problem here is that Aaron is using DHEA for its side effects.
Side effects with any drug happen. They are usually listed according to how common they are, with particularly common ones being noted separately.
I did find a little information on the frequency of some of the side effects, but can't list it here.
My biggest concern is that I can't get any proper or credable information on what constiutes an overdose.
Everything has an overdose. Even tea!! But I can't get a credable source to say what the overdose of DHEA is.
