On cortisol and gains.......
Here's a discussion between Bill Roberts and myself on the issue.
(Bill) GR 'blockking' AAS

Does you have any info on different AAS and their affinity for the glucocorticoid receptor? How much do you think this property contributes to the over-all effectiveness of the AAS? Andy
Bill Roberts 2002-05-21 13:54:54
I would have to go look stuff up again to give you much of an answer on details of different androgens. (And you'd probably be as quick as me in doing so.) On the question of whether I think it's important to effectiveness, I don't think so. After all, if you want to, you can drive cortisol levels as low as you might like with Cytadren, and this does not improve efficacy of a cycle though it certainly does give you joint pains. So I don't see why an androgen being a glucocorticoid receptor antagonist would be of any more value in increasing gains.

I meant to say while dieting, to possibly decrease the expression of gluconeogenic and proteolytic genes. This may shift metabolism a little more toward fatty acid oxidation and maybe slight ketone body production-- neither of which would make a measurable difference in fat loss, but MAY make a difference as far as muscle preservation.

To test this out, try taking Cytadren at doses like 500-1000 mg/day. This will reduce your cortisol. Not to your benefit, I think, but it's something you can try and determine for yourself. This I think would much more clearly answer the question of whether reducing cortisol effect is of value in whatever situation you wish to apply it to, than would trying an androgen which also has some anti-glucocorticoid effect: because in the latter case, you have another factor confounding estimatation of the effect of the antiglucocorticoid activity.

Eeewwwwww.... I know of too many benefits from cortisol to be willing to take cytadren (is that the side-chain cleaving enzyme inhibitor?).. The reason why I asked this question in the first place was because I have read a number of papers that suggest that GR antagonization MAY lead to some kind of over-all greater effect from the AAS.. However, these claims were from studies using HRT doses of androgen-- nothing like what would be considered 'effective' for a BBer... I began to wonder if muscle loss while dieting (the kind of diet that lowers the electro-chemical gradient in a certain inner membrane, if you know what I mean) was predominantly due to increased gluconeogenesis. I don't remember the specifics, but there's this so-called pyruvate-alanine cycle works with the liver and muscle and supplies the 3-carbon skeleton's needed for glucose generation in the liver. Not sure about this (I have NO access to any resources right now) but I believe that t3 and cortisol are the main players in the manufacture of protein degrading enzymes for the eventual liberation of alanine... I think fatty acid oxidation enzymes are synthesized in response to other hormones besides cortisol such as epi' and maybe glucagon (last time I checked, the latter was a potent activator of lipase activity IN VITRO, although this had not been demonstrated in vivo). Anyway.. I think t3 is less of a concern as far as muscle loss since it increases protein synthesis (although, apparently not as much as it does degredation). What's YOUR opinion? I trust any gut feeling you have over what some dude who took cytadren has to say. (you know that) Most BBer's analytical methods aren't even logical, let alone experimentally meaningful

The "side effects" from Cytadren are due to the usually-intended effect of decreasing cortisol. If the hypothesis is that reducing effects produced as a consequence of cortisol receptors binding cortisol (by providing an antagonist) will have some desired effect, but the antagonist confounds the issue by having other agonist properties of its own, then this can readily be tested by simply reducing the amount of cortisol and seeing if this gives the desired effect.
But instead, the effect is more or less as you described for higher doses of Cytadren, namely, Eeewwwwww....
"So it does not seem reasonable to attribute benefits of anabolic steroids to reducing cortisol receptor activity, since a known means of reducing this activity does not give the claimed benefit in individuals with normal cortisol levels in the first place." (Bill Roberts)
