Hi Sweettooth,
Yes, I have taken DHEA. I'm sure that you have found in your research that not enough is known about the effects of DHEA, good or bad, mainly because the lack of research. You can only buy it online in the UK and should be very careful to buy it from a reputable company.
I have low levels of testosterone and DHEA ( recent blood tests show I have 1/2 the minimum). Last year, I had even lower energy levels, which was probably due to an underlying infection. I have been seeing a therapist, who specialises in sexual problems, because of my non existent libido. I was very distressed as I didn't have to energy to get to the USA to see my son. She recommended I took 100g per day as a temporary measure. Within a week or so I felt a lot better, well enough to travel. However, my energy of levels crashed again while away. Bear in mind there were other health issues going
I suggest you find out as much as you can. Probably better to try a lower amount at first. They are sold in different strengths, eg 50g. If I had not found help for my health issues, I would have given DHEA a try again, despite any risks. I'd rather go for quality of life, than quantity.
Is your GP knowledgable and helpful? Have you discussed this dilemma with him/her? There may be a good reason why Clonidine was prescribed, which was not explained to you. Your GP should be able to help you about this.
