[Determined]

Dear all,

I am not a chemist but a consumer who has bought a DHEA supplement and is a little worried about the quality of it. I contacted the company producing it, asking them for a Certificate of Analysis and the MSDS. The customer service employee (always the same person) first asked me where I'm from. After he got my reply, he wrote: "Unfortunately, we are not able to provide a Certificate of Analysis for this product."

My question: who knows if it is required by law for companies to possess a MSDS for DHEA supplements? Similarly, for a Certificate of Analysis? I did Google this but since I'm not from the USA nor native English, it is hard for me to get to a good and understandable source of information.

  For people wondering  why I'd order a supplement from the USA: 

In my country, it is not allowed to buy DHEA online, however, I still had a bottle of a brand that seems reliable to me (Life Extenstion). I am using it to help get pregnant, since DHEA boosts your hormones and is considered safe for OTC sales in the USA. I am 40+ years old and didn't have any succes the last 3 years (only 3 early miscarriages to my great sadness). Now, after using the DHEA for 2 months, I am pregnant. You can probably understand that I do not suddenly want to discontinue use of this supplement but rather slowly wean it off. Unfortunately, I can't order the exact same supplement anymore :-(
The only place I could still get it from, was this company that doesn't seem very helpful in their customer service. When I asked him before about the quality of their product, he replied:

"Our DHEA is produced in a laboratory from a vegetal saponin called Diosgenin. We use Wild Yam roots, which is the most concentrated known source of phytoestrogen diosgenin. Our DHEA is 99.5% purity and pharmaceutical grade Type 1."

Are there any other questions I could ask, or do I have any right to ask for a certificate of some kind?
