Dobry Art Slawek.
W praktyce jak i w badaniach tak jak napisales na dzien dzisiejszy liczy sie jedynie dhea i androstenetriol. Z tych hmmm lagodniejszych bo jak wiadomo kazdy inny steryd anaboliczno androgeniczny dziala na obnizenie kortyzolu.
Jednak szkoda ze tak malo osob bierze sobie do serca ze imho za
spadki po cyklu na SAA odpowiada niski poziom tescia i wysoki kortyzolu - idealna mieszanka kataboliczna dla miesni
Biorac Sermy/AI oraz DHEA/Androstenetriol atakujemy ten stan z 2 strn na raz i PCT idzie z górki.
Ja odkad dodalem Dhea na PCT, to totalnie zmienily sie moje spadki po cyklach. Sa one naprawde minimalne.
Ogolnie jak ktos nie chce bawic sie w powazne sterydy i kox to mam dla niego cos lagodniejszego - zbudowanie bazy anabolicznej na w miare naturalnej puli hormonow(a raczej ich regulacji). Wszystko to bez igerencji (blokady) hpta
20mg nolvadexu przez 2-3 miesiace
100-200mg dhea przez 2-3 miesiace (2 razy dzienie dawka dzielona)
Formestane lub inne AI (ale juz nie ATD heheheh o tym kiedy indziej) tez przez 2-3 miesiace
serm podbija tescia
Dhea obniza kortyzol
AI zapobiega konwersji tescia do estro robiac lepsze ratio testosteron-estradiol a do tego AI jak wiadomo obniza SHBG.
Srodowisko idealne do budowy miesni bez blokady hpta
, obciazania watroby, itp. W porownaniu do siegania po SAA jest to lajcik a naprawde mozna osiagnac na nim fajne rezultaty
Troche nie na temat ale co tam heheh
Slawek moze nawiazemy wspolprace - Ty bedziesz pisal teorie a ja sprawdzal ja w praktyce

Androstenetriol: An Interesting DHEA Metabolite
By Thomas Incledon, PhD(c), RD, LD/LN, RPT, NSCA-CPT, CSCS, CFT
What is this stuff
In this article, I will dig deep into the research and present all of the current scientific information on androstenetriol. While things may get a little technical, don’t split your Speedos. I’ll spell it out in simple terms and you will understand all that the scientists know.
Which is the real androstenetriol?
Triols are simply steroids with three hydroxyl (OH) groups attached to their carbon structures. After reviewing through every study I could find, it appears that there are at least 3 possible androstenetriols:
1) 5-androstene-3 beta, 16 alpha, 17 beta-triol
2) 5-androstene-3 beta, 7 alpha, 17 beta-triol
3) 5-androstene-3 beta, 7 beta, 17 beta-triol
All of these agents are structurally classified as steroids. The first one has been isolated from human placenta and can be converted into the estrogen estriol [1]. This 16 alpha-androstenetriol version was first isolated from the urine of a patient with cancer of the adrenal glands in 1943 and was later identified in human umbilical plasma [2] and also isolated from the urine of infants [3] and men [4]. There isn’t much known about the function of this triol. It appears to inhibit the enzyme 16-alpha hydoxylase [5] and can be produced from DHEA by human macrophages (specialized white blood cells) [6]. Until more is learned about this agent, it would be best to avoid the 16 alpha-androstenetriol version.
The second and third versions of androstenetriol are basically isomers of each other. They have the same chemical formula, but the difference is in the orientations of the hydroxyl groups attached to the 7th carbon. Most of the research appears to be on the 7-beta androstenetriol, so this will be the focus of this article and from here on referred to as androstenetriol.
Synthesis of androstenetriol (5-androstene-3 beta, 7 beta, 17 beta-triol)
Research using abdominal skin from men and women indicates that androstenetriol can be formed from two separate pathways [7]. First, DHEA can be converted into 5-Androdiol (5AD or 5-androstene-3 beta, 17 beta-diol). 5AD in turn can be converted into androstenetriol (5AT). 5AT can also be formed from the 7-keto version of 5AD. To make this easier to follow here is a chart:
DHEA
5-androstene-3 beta, 17 beta-diol (5AD)
/
5-androstene-3 beta, 7 beta, 17 beta-triol (5AT)
/
and/or
/
5-androstene-3 beta, 17 beta-diol (5AD)
/
5-androstene-3 beta, 7 alpha, 17 beta-triol
/
7-keto-5-androstene-3 beta, 17 beta-diol
/
5-androstene-3 beta, 7 beta, 17 beta-triol (5AT)
The arrows indicate which way the reactions can proceed. The synthesis of 5AT comes primarily from the direct conversion of 5AD to 5AT. Since both 5AD and 5AT can come from DHEA, they are referred to as DHEA metabolites in the literature, hence the title of this article.
A Little 5AT History
It was established that DHEA could counteract the effects of glucocorticosteriods (like cortisol) and boost immunity [8]. Later after realizing that DHEA could be metabolized by skin and brain into 5AD and 5AT [9, 10], researchers started to investigate the DHEA metabolites. In vitro studies with mice lymphocytes (specialized white blood cells) indicated that 5AT strongly counteracted cortisol and boosted lymphocyte activity, whereas DHEA did not counteract cortisol and suppressed lymphocyte activity [11]. Additional in vitro studies demonstrated that 5AT was more effective against a viral infection in mice than its precursor 5AD [12]. 5AT potentiated immune responses and counteracted the immunosuppressive actions of cortisol. The researchers also found that the 7-beta version of 5AT was more potent than the 7-alpha version of 5AT.
Immune Boosting Effects of 5AT
Traditionally when we learn or discuss the immune system, it is treated as a separate physiological system from the endocrine and nervous systems. In 1988 Loria et al reported that DHEA could regulate immune responses against lethal virus and bacterial infections [13]. Over the next two decades, scientists started piecing together a process that involved components of the nervous system, endocrine system, and immune system. 5AT appears to have a dose response effect. Using mouse spleen cells and concentrations ranging from 5 nanomoles per liter to 5 micromoles per liter, 5AT stimulated the production of the cytokines interleukin-2 (IL-2) by 111-122% and interleukin-3 (IL-3) by 30-47% [12]. T-cells and B-cells were also simulated by this DHEA metabolite. In other studies using mouse macrophages, 5AT increased tumor necrosis factor alpha (TNF-alpha) and IL-1 secretion while not influencing IL-6 production [14].
The data I have reviewed thus far is all from rodents (particularly mice). Since 5AT boosts the immune system of rodents, one asks the logical question: can this data also be applied to humans? Since 5AT is present in a variety of mammals, including humans, it seems plausible that 5AT could boost the immune response in humans. This needs to be confirmed by research and questions as to how much is needed in humans to get a decent effect need to be answered.
Antiglucocorticoid Effects of 5AT
DHEA and its metabolites (5AD and 5AT) counteract the stress-induced immunosuppressive action of glucocorticoids [15]. This results in stronger responses to immune system challenges. Hydrocortisone (cortisol) classically is used to suppress immune function in cells treated with an immune challenge. DHEA was unable to counteract the immunosuppressive effects of cortisol, while 5AD counteracted it only at high doses. 5AT significantly counteracted the immunosuppressive effects of the glucocorticoid on lymphocyte growth and cytokine production [15]. Research overall indicates that in the body, DHEA, 5AD, and 5AT may have some similar functions, while in cell culture studies their effects are dramatically different from one another. In another study, 5AT counteracted the down-regulatory effect of hydrocortisone on macrophages and may function to counterbalance glucocorticoid function [14].
An abstract was presented in 1997 at the Conference on Cortisol and Anti-Cortisols in Las Vegas Nevada. In vitro work indicated that 5AT counteracted the immunosuppressive effects of glucocorticoids on immune cells from patients with hypercortisolemia [16]. This data is preliminary and has yet to be published (or is not indexed on any database I searched through).
tissue weights during a sever infection. Could this have potential application for bodybuilders and athletes? The obvious application would be to marathon runners, triathletes, and wrestlers who are traditionally overtrained. I am working on some projects right now and hope to have a definitive answer in the future as to how Androstenetriol can be used by athletes. Keep reading ASMJ and you’ll be the first to know.
