Boron vs DHEA
Two mild hormone-adjacent supplements marketed for testosterone and vitality — a trace mineral that nudges free T via SHBG, and an adrenal prohormone that falls with age.
Boron
Small RCTs show boron nudges free testosterone up via lowered SHBG — a real, mechanistically plausible effect that gets oversold as a standalone 'testosterone booster' when the effect size is modest and the trials are tiny.

Dehydroepiandrosterone
Real replacement value in true adrenal deficiency (and FDA-approved as intravaginal prasterone), but the anti-aging trials were negative and it barely moves healthy young men's testosterone.

Our verdict
Boron's small RCTs show it lowers SHBG and modestly raises free testosterone — a real, mechanistically clean effect, oversold as a standalone 'testosterone booster.' DHEA has a genuinely different profile: real value in people with confirmed deficiency (and an FDA-approved intravaginal form for a specific indication), but a weak record as a general anti-aging supplement in people without deficiency. Neither produces the kind of testosterone change a prescription therapy does.
Boron fits if
You want the more mechanistically specific, lower-cost intervention and have no interest in a broader hormone-replacement conversation.
DHEA fits if
You suspect an actual adrenal-hormone deficiency rather than wanting a general testosterone nudge — get levels checked first.
