Boron and DHEA, a caution.
Both boron and DHEA can independently raise circulating androgen and estrogen levels. Boron tends to increase free testosterone and estradiol (in part by lowering SHBG), while DHEA serves as a direct precursor that the body converts into those same hormones. Stacking them can produce a larger combined rise in sex hormones than either alone, which is desirable for some users but can also amplify estrogen-related or androgen-related side effects.

Caution
What is happening. Both boron and DHEA can independently raise circulating androgen and estrogen levels. Boron tends to increase free testosterone and estradiol (in part by lowering SHBG), while DHEA serves as a direct precursor that the body converts into those same hormones. Stacking them can produce a larger combined rise in sex hormones than either alone, which is desirable for some users but can also amplify estrogen-related or androgen-related side effects.
Mechanism. Boron supplementation has been shown in small human studies to raise circulating sex steroid hormones, with reported increases in free testosterone and estradiol attributed partly to reduced sex hormone binding globulin (SHBG) and altered steroid hormone metabolism and clearance. DHEA is an upstream adrenal precursor that converts to testosterone and estradiol via peripheral steroidogenesis. Acting on the same steroidogenic pathway from different points, their effects on downstream androgens and estrogens tend to be additive rather than independent.
Recommendation. If stacking, start DHEA at the lowest effective dose (commonly 10 to 25 mg/day) rather than higher doses, and keep boron in the typical supplemental range (around 3 to 10 mg/day). Consider monitoring testosterone, estradiol, and SHBG if using both for more than a few weeks, especially in hormone-sensitive individuals. Women, anyone with a history of hormone-sensitive conditions (breast, ovarian, uterine, or prostate concerns), and those on hormone therapy should consult a clinician before combining. There is no need to separate the doses by time; the consideration is cumulative hormonal effect, not absorption.
