DHEA (Dehydroepiandrosterone) is a supplement that promotes optimal hormone levels. It's sold at Wegmans and would be near the fish oil. And its an illegal substance with the USADA.
It's also produced naturally in the body.
I am reserving judgement. I'd like to know what marker appeared outside normal limits and what AB supposedly took.
Wegman's carries stuff that could cause a failed drug test.
Fifteen years ago, I popped a borderline A1C (6.0)
Doc suggested several things, including Vitamin D3 and DHEA. I tried it for a while, my A1C has bounced around between 5.3 and 5.9 and since that's high normal I dropped it. Although it can be ingested, the body naturally produces in the adrenal gland.

What Should Athletes Know about DHEA? | USADA
While not included under the Controlled Substances Act, athletes should know that DHEA is considered a prohibited anabolic agent in sport.
It's banned whether or not prescribed, despite the fact that results of testing on effects of strength are mixed
I never got an increase in strength or musculature from it-and as far as I know, my NCAA -National Coalition of Aging Accountants doesn't ban it for my events (Ledger Wrestling and Spreadsheet Gymnastics).

DHEA
Understand what DHEA is and the possible side effects associated with this supplement.
At one point there was a push to classify it as an anabolic steroid.
I am not saying AB used DHEA. Based on the claims made, I'd don't think this would be it. Let's see if the test results are the potential result of something "next to" or near fish oil.
