A tidy, transparent formula at a premium price and a four-capsules-a-day commitment. Prime Male lists its doses and covers the sensible bases — vitamin D, zinc, magnesium, boron, K2, ashwagandha — plus some weaker bets like D-aspartic acid and luteolin. Nothing here is junk, but nothing is a breakthrough either, and at around $2.30 a serving it's one of the priciest ways to take what are, mostly, cheap individual nutrients.
Doses disclosed, no proprietary blend. The vitamins and minerals sit at reasonable levels and matter if you're deficient; boron and ashwagandha have the most support for anything testosterone-related. You take four capsules a day to hit the label, so factor that into the real cost.
For someone who wants a covers-the-bases formula in one bottle and is happy to pay for the convenience. If you already eat well and aren't deficient, you'd get most of the benefit from cheap standalone vitamin D, zinc and ashwagandha.
