My Endocrinologist gave me a bottle of Douglas Laboratories Pregnenolone Supplements after she had ran a batch of labs on me. It was found that I had low levels of DHEA and pregnenolone, as well as having low T. I'm in my mid-years; so it was expected that my levels were going to be a bit low. I started taking one tablet in the morning and after only a month, low and behold, I was starting to feel better than I had in a long time. I had more energy, I wasn't falling asleep during the day, and I was able to do my daily workouts again. My doc ran the labs again after taking the full bottle of 60 tablets. My levels were higher than before. I was told it's going to take a while to get my levels back to normal, but I can definitely tell its working. Douglas Laboratories supplements can be a bit pricey, but they are approved by my Doctor. I don't normally spend the extra money for the higher end supplements, but for the first 60 days of taking this supplement, it has turned my life around.
