This is marketed as another testosterone booster, as it is a precursor in testosterone synthesis. The problem is that pregnenolone is also a precursor to other steroid hormones, including progesterone, cortisol and aldosterone, all of which are disadvantageous to a bodybuilder. Which hormone pregnenolone ends up as is governed by the pituitary gland in the head, via negative feedback. If there is no stimulus for testosterone production, then testosterone will not be produced from the increased levels of pregnenolone. Conversely, higher levels of cortisol or the other hormones could be produced if there is a stimulus for their manufacture and pregnenolone is present. In this case, not only may this supplement be of no use to a bodybuilder, but it may, in fact, be catabolic. Avoid it.
