1- Androsteronetm (1-DHEA) is a non-methylated (non 17aa) pro-steroid that must convert to 1-androstenediol (1-AD), 1-androstenedione (original 1-AD) and/or 1-testosterone to be active. The double bond in the 1st position seems to slightly enhance its ability to resist excretion by the liver.
1-Androsterone occurs naturally in the body, and is a naturally occurring metabolite of DHEA. (2) The 17b-HSD enzyme converts 1-Androsterone to 1-Androstenediol, and the 3b-HSD converts it to 1-Androstenedione. Both of these 1-AD metabolites can then be converted to 1-Testosterone. Although the 1-AD metabolites are known to have some anabolic and androgenic effects on their own, 1-Testosterone is probably where most of the effects come from with this steroid.
There is no conversion to estrogen so users will not experience bloat with this compound, nor will it have a dramatic effect on blood pressure. However one unique side effect that users have reported with this compound is a feeling of lethargy. (It appears that stacking 1-Androsterone with a nuero-active hormone such as DHEA can help reverse this effect).
1-Androsterone (and primarily its metabolites) have relatively potent androgenic effects, therefore gyno is almost never an issue. However, because of the androgenic potency, this compound could pose a mild hair loss risk for those prone to MPB. Because this steroid is non-17aa there should be less concern about it negatively affecting the HDL/LDL ratio.
Results from this compound generally take a couple weeks to be realized. Moderate gains of lean muscle mass and strength can be expected, but users should not expect rapid increases in size or weight with this compound since extra-cellular and intra-cellular water retention are very minimal. This makes the gains from this steroid fairly easy to maintain post cycle.
1-Androsterone will stack well with almost any compound. For more dramatic gains in size and strength it is recommended to stack this compound with an aromatizing steroid or possibly one of the progestational compounds listed elsewhere.
