I swear by pregnenolone, it is very versatile hormone and helps out adrenals and also pregnenolone on its own can sort out neurotransmitters- interesting thing about pregnenolone supps is that some brands work better for some and worse for others. Topical is more effective, but some orals work allright. Pregnenolone is a great addition to any cycle and TRT as well. Out of cycle- pregenolone itself is not supressive but it cascades into other hormones which then can cause supression- if right dosage is used it could be run indefinitely without supression, but finding "right dosage" is hard task. Other thing with pregnenolone is that higher dosage is not always more efficient- when we use higher doses liver produces more enzymes- so it goes into waste.
For anyone with adrenal fatigue- pregnenolone is a Godsend, for older folks is also very beneficial and it really improves quality of life.
