I was speaking to my Doctor about buying fat burners. we talked about different supps and things ot watch out for.
he mentioned GUGGULSTERONE.
The hypolipidemic natural product guggulsterone is a promiscuous steroid receptor ligand.

Guggulsterone (GS) is the active substance in guggulipid, an extract of the guggul tree, Commiphora mukul, used to treat a variety of disorders in humans, including dyslipidemia, obesity, and inflammation. The activity of GS has been suggested to be mediated by antagonism of the receptor for bile acids, the farnesoid X receptor (FXR). Here, we demonstrate that both stereoisomers of the plant sterol, (E)- and (Z)-GS, bind to the steroid receptors at a much higher affinity than to FXR. Both stereoisomers bind to the mineralocorticoid receptor (MR) with a Ki value of approximately 35 nM, which is greater than 100 times more potent than their affinity for FXR. Both (E)- and (Z)-GS also displayed high affinity for other steroid receptors, including the androgen (AR), glucocorticoid (GR), and progesterone receptors (PR) with Ki values ranging from 224 to 315 nM. In cell-based functional cotransfection assays, GSs behaved as antagonists of AR, GR, and MR, but as agonists of PR. Agonist activity was also demonstrated with estrogen receptor (ER) alpha; however, the potency was very low (EC50 > 5000 nM). In addition, GS displayed activity in functional assays in cell lines expressing endogenous AR, GR, ER, and PR. These data suggest that the variety of pharmacological effects exhibited by GS may be mediated by targeting several steroid receptors.
Basically in English he told me it's bad because :
basically that it blocks the androgen receptor
and that it activates the progesterone receptor, which I beleive is why people feel "hot", basically a menapausal "hotflash".
In my head I was like screw burning fat, I will take Hot flshes any day if it helps block androgen receptors.
Any of you guys have any info on it or think guggulsterone may actualy help with hairloss??? ( I never asked my Doctor about it. Too shy)
