Supplementation with DHEA to CFS patients lead to a significant reduction in the symptoms of CFS: pain (improved by 18%, p = 0.035), fatigue (decreased by 21%, p = 0.009)), activities of daily living (improved by 8.5%, p = 0.058), helplessness (decreased by 11%, p = 0.015), anxiety (decreased by 35%, p < 0.01), thinking (improved by 26%, p < 0.01), memory (improved by 17%, p < 0.05), and sexual problems (improved by 22%, p = 0.06) over the period of the trial.
500-1000mg Rhodiola and 100-200mg DHEA. (My experience)
For males worried about an increase in Oestrogen can consider taking DIM to increase the ratio of Testosterone to Oestrogen.
Works instantly whenever you feel tired, it's like a miracle. Pretty reliant on this because my inflammation generates sudden fatigue attacks.
