I've had a very similar experience as you docall18; and I've also been at it for years: trying to figure how to best quell oestrogen/improve thyroid function. Thyroid (in all the usual variants), pregnenolone (both oral and topical) and oral DHEA almost always led to oestrogenic effects/thyrotoxicity and seldom a sustained elevation of body temperature. However, of late I've become noticeably 'dry' by combining high-dose caffeine (lots of coffee with copious amounts of sugar, Red Bull) and topical DHEA dissolved in warmed coconut oil. Haidut's claims regarding the relative androgenecity of topical DHEA certainly seem consistent with my own finding.
Cheers for the tips! Ya I have also found caffeine one of the few supps that does what it purported to do. I take approx 700mg/day and i know estrogen would be a lot higher without it. As i reduce my T3 dose to approx 25mcg/day, i will double caffeine.
I do have topical Dhea and will give it a go at low dose to see what happens.
